Since the first Amazon Prime Day in 2015, the retailer has scaled its summer sale to record-breaking heights. And for the first time in two years, Prime Day 2022 is back to happening in July — specifically, on Tuesday, July 12, and Wednesday, July 13. The retailer hosted Prime Day 2021 in June, the earliest the event has ever occurred, and Prime Day 2020 in October, the latest date on record. The event being held in July this year is a sign that Amazon is returning to its “standardized approach” to Prime Day, according to Joseph Hansen, the founder and CEO of marketing agency Buy Box Experts — before 2020, Amazon held every Prime Day in July and shoppers could plan accordingly.

But that doesn't mean Amazon is out of the woods after facing challenges the past two years, including Covid-related delays and global supply chain issues. Countries around the world, including the U.S., are currently seeing high levels of inflation, and the cost of items like groceries, gasoline and household products like cleaning supplies is increasing. Retailers are already reporting seeing shifts in shopping habits in part due to inflation. Experts said all of this may impact how much consumers are willing to spend on Prime Day and the event's overall performance in 2022.

“Consumers are spending more on food and less on general merchandise due to inflationary pressures,” Hansen said. “I think that is a key indicator, and that will affect Prime Day.”

Hansen said he still expects to see year-over-year growth for total Prime Days sales, but not by as much as in years past. This is also a trend Amazon saw between 2020 and 2021: Market research firm Digital Commerce 360 estimates that Amazon sold $11.2 billion worth of goods during Prime Day 2021, up only 7.7% from $10.4 billion in 2020. Between 2019 and 2020, the retailer saw a 45.2% jump in Prime Day sales year over year.

Despite a smaller bump in sales, Prime Day 2021 was a success — it dominated a usually dormant online shopping period, driving traffic not only to its site, but also to other retailers that host competing sales. Prime Day 2021 was particularly lucrative for Amazon third-party sellers, nearly all of which are small and medium-sized businesses, according to Amazon. The retailer said that the event was the biggest two-day period ever for Amazon’s third-party sellers.

As Prime Day 2022 approaches, we consulted experts about the growth of Prime Day and looked back on its history. We also compiled some of the top-selling items during Amazon Prime Day events worldwide, from Instant Pots to the Echo Dot.

Looking ahead to Prime Day 2022

According to data from RetailMeNot, 88% of Americans plan to shop on Amazon during Prime Day this year and 47% are waiting for Prime Day to make their biggest purchases of the year. And according to Hansen, Amazon “penetrates” households very well, which is one factor that may help it perform on Prime Day this year despite the challenges it’s coming up against. Between Alexa devices, the Amazon app, services like Prime Video and Music and more, Amazon has ample opportunities to advertise and remind members about Prime Day, which may help drive shoppers to the sale.

However, Hansen said it won’t all be smooth sailing for Amazon this year. “The headwind that Amazon will face is other retailers running competing sales,” he explained. “Their presence is a lot bigger than it was even just last year. They now run their own version[s] of Prime Day to try to siphon off a lot of that excitement and traffic.” Shoppers are already planning to browse deals across retailers on Prime Day — according to, RetailMeNot, 19% of Americans plan to shop at other retailers during Amazon’s sales event.

Despite reports that e-commerce transactions recently dropped a bit while in-store transactions increased, Hansen said it’s not over for online shopping. He said people are being more cautious when it comes to spending due to concerns about the economy — online or otherwise.

“I don’t think there’s been some huge, visceral shift in e-commerce spending,” Hansen said. “It’s really that people are not spending as much on discretionary items because they’re spending more on food.”

Amazon is adding new ways for Prime members to jump on deals year-round, which may come in handy during Prime Day. For example, Alexa can now notify you up to 24 in advance of a deal becoming available for an item on your wish list, in your shopping cart or saved for later. You can ask Alexa to remind you when a deal goes live and give the virtual assistant permission to order the item on your behalf once the deal goes live using your account’s default payment and delivery address.

As for the types of deals offered during Prime Day 2022, Hansen said he expects sellers to offer steep discounts as they have in years past. For example, while Prime Day doesn't officially start until July 12, shoppers can find deals beginning on June 21, including up to 55% off select Amazon devices. Amazon also said items from brands like Beats, Casper, SharkNinja, Sony and more will be discounted during Prime Day. However, there may not be as many products on sale overall. Sellers may target specific items they want to move out of their inventory and offer savings on those, especially if they find themselves with a surplus of items.

What is Amazon Prime Day?

Prime Day is an exclusive sale for Amazon Prime members — shoppers pay $139 a year to receive benefits like free expedited shipping on eligible purchases, free movies and TV shows through Prime Video (available on its own for $9 a month) and unlimited access to reading material on any device through Prime Reading, among other benefits. During Prime Day, select products from a variety of brands are greatly discounted, from Amazon-owned electronics to clothing and homewares. Additionally, while Amazon regularly offers Lightning Deals — short-term deals on specific products that could last hours or days — they’re exclusive to Prime members during Amazon Prime Day.

The first-ever Prime Day event took place on July 15, 2015 as a way to celebrate the company’s 20th anniversary, according to Amazon’s blog. The first Prime Day lasted 24 hours and gave access to members in nine countries: the United States, United Kingdom, Spain, Japan, Italy, Germany, France, Canada and Austria. Since 2015, Palmer said, Amazon Prime Day has grown “exponentially.” In 2020 and 2021, Amazon hosted Prime Day in 20 countries around the globe, and it plans to open access to Prime members in over 20 countries this year. Prime members in Poland, Sweden and Egypt can shop the sale for the first time in 2022.

Amazon Prime Day total sales have notoriously surpassed those on Black Friday and Cyber Monday for the company, Palmer said. But selling products isn’t the only focus of Prime Day. Amanda Bourlier, who oversees global retailing research at market research company Euromonitor International, said Amazon uses Prime Day as a way to attract new Prime subscribers, pitching to them Amazon’s “ecosystem of consumption,” meaning all of the services Amazon provides shoppers, like access to music and video streaming services and grocery delivery. “A Prime member probably doesn’t just shop from,” Bourlier said. “In addition to shopping on Amazon, they can buy groceries from Whole Foods, listen to audiobooks with Audible, subscribe to Kindle Unlimited, watch Amazon Video and use Amazon Echo speakers.” Prime Day, then, acts as a sort of doorbuster deal to get shoppers close to everything else Amazon Prime.

Palmer said Prime Day is unique in its scale because it’s a manufactured event created by the company. The sale does not coincide with the holiday shopping season, unlike Black Friday and Cyber Monday. Amazon Prime Day is traditionally held in mid-July, which is a strategic decision on the company’s part: The summer is typically a slower period for retailers. Amazon Prime Day is an attempt to remedy that. In fact, Prime Day has become so big that it’s forced Amazon competitors like Walmart, Macy’s and Target to respond by changing the timing of their own sales and deals. Since Prime Day usually falls in July, for example, Macy’s runs its Black Friday in July event then. And with Walmart+, Walmart’s own version of Amazon Prime, the stakes are higher than ever.

“Prime Day is no longer just a day for people to purchase cheap items on Amazon,” Palmer said. “Quite frankly, it has completely altered the retail calendar.”

Additionally, Prime Day is positioned well before the holiday shopping season — usually, anyway. James Thomson, a partner at Buy Box Experts, said Amazon wants to get non-Prime customers to buy a Prime membership during the summer, prompting them to handle their Christmas shopping — and even back-to-school and Labor Day shopping — through the retailer. “The most important thing Amazon can do is drive loyalty to the Amazon marketplace,” Thomson said. “The company wants to get consumers to say, ‘I’m not going to walk into a physical store because it’s so much easier to buy on Amazon.’”

While Prime Day is highly profitable for Amazon and its sellers, Thomson said there’s another reason it’s such an important event for the company. He said Prime Day is a “massive dry run” for quarter four, which is when the holidays take place. Thomson, formerly the business head of Amazon Services, the Amazon division responsible for recruiting sellers to the Amazon marketplace, explained that Prime Day creates an artificial surge in orders, a similar increase to what the retailer experiences between November and December.

“One of Prime Day’s primary focuses is doing a test drive to make sure its operations work properly,” Thomson said. “It’s a nice warm up, and at the end of the day, it’s something Amazon has to do for itself.”

Bestselling Amazon Prime Day products

The bestselling products on Prime Day vary from year to year and differ from country to country, and that’s not just the result of differing buying habits — Amazon’s Prime Day offerings in one country aren’t always reflective in another.

“I don’t know what the secret sauce is to becoming the bestselling item on Prime Day,” Palmer said. But she points to factors like the deal itself being well advertised, or just that “it’s a good deal, plain and simple.” But, consistently, Amazon said they see record-breaking sales for their devices, from Fire tablets to Alexa-enabled tech.

To give you an idea of some of the most successful deals during Prime Day over the past three years, we compiled a few bestsellers by country below. Amazon does not provide information about bestsellers for every country that Prime Day is held in each year, and some products are specific to certain countries, like a certain dishwashing detergent brand, for example. We chose to highlight a handful of Prime Day bestsellers that are widely available. For 2019, 2020 and 2021, we included top selling products globally and in the U.S., as well as in a variety of other countries so you can see what items people are shopping for on Prime Day worldwide.

What to shop for on Amazon Prime Day

Although Thomson said Prime Day offers “legitimate discounts” on products, the sale does not offer customers discounts on “a smorgasbord of items.” At its core, he said the sale centers around Amazon products, whether that be a Kindle or a Fire Stick. Brands big and small also offer plenty of deals on other tech, fashion items, toys, beauty products, small kitchen appliances and more, but shoppers don’t know exactly what’s going to be discounted until the day the sale occurs. Because of this, Thomson said, shoppers often buy products spontaneously. Of course, online shopping guides and recommendations from publishers like Select and our friends at Shop TODAY aim to help you and shoppers at-large approach the sale as informed and prepared as can be.

Prime Day also serves as a trial run for small brands. “During Prime Day, shoppers will buy products that may not be from brands they’re familiar with because of big discounts,” Thomson said. “Amazon wants you to try that product for the first time.” To encourage shopping from small and medium-sized businesses, Amazon hosted its Spend $10, Get $10 promotion in the two weeks leading up to Prime Day 2021. Prime members who bought $10 worth of items from small businesses on Amazon got $10 credit to use during Prime Day. Overall, shoppers spent over $1.9 billion on more than 70 million small business products during the two-week period. Amazon said this marks more than a 100% year-over-year increase on sales compared to the same Prime Day October 2020 promotion. In 2022, Amazon is also promoting shopping from small businesses by hosting a handful of promotions — from June 21 through July 11, for every $1 spent on eligible small business products, shoppers will receive a chance to win prizes.

Additionally, during Prime Day, some brands offer products that previously did not sell a lot of units, Thomson said, enabling heavier discounts on those specific items. The same thing happens on Black Friday — brands ask themselves what they have a lot of and sell anything in surplus at a lower margin (a common trope for any sale at any time and by any retailer). For example, a brand may discount a TV on Prime Day but it might be an old model.

Amazon Prime membership 101

Amazon Prime launched in 2005. It offered members benefits like two-day free shipping, which, at the time, seemed like a pipe dream, Bourlier said. Fast delivery was — and still is — a factor that motivates people to become Prime members, in addition to the variety of products Amazon offers shoppers to purchase in one place.

This year, Amazon raised the price of its Prime membership and Prime student membership. It now costs $15 a month (up from $13 a month) to be a Prime member, or you can pay $139 annually (previously $119). The Prime Student membership also increased in price from $59 a year to $69 a year. Amazon also offers a discounted Prime membership ($7 per month) for those who qualify for certain types of government assistance programs, like EBT and Medicaid.

Over the years, Amazon has expanded the benefits Prime members get, like access to Prime Video, Gaming, Music and more. Notably, Amazon bought the grocery store chain Whole Foods Market in 2017, leading to exclusive savings both in stores and online for Prime members. Members were previously entitled to free two-hour grocery delivery through Whole Foods Market and Amazon Fresh, but in Oct. 2021, Amazon added a $10 service fee for deliveries from Whole Foods Market. The price hike for Prime memberships and grocery deliveries may be due to inflationary pressures and the increased cost of gasoline, Hansen said, since this makes transporting products more expensive.

One of the newest Prime membership benefits is Buy with Prime, which allows Prime members to order items through other retailers’ websites using payment and shipping information stored on their Amazon account. The service also extends the free and fast delivery options members get through Amazon.

As Amazon continues to add to the benefits Prime members get, Bourlier said it sets the bar for other retailers looking to start loyalty programs. Added benefits also “lock” shoppers into the Amazon ecosystem. “Amazon Prime wasn’t the first retailer with a loyalty program, but it was one of the first retailers to imagine how loyalty programs might look in an ecommerce landscape,” Bourlier said. “Amazon is also often the first retailer to offer specific features to shoppers, like free two-day shipping.”
