Prime Day 2021 was yet another record-breaking, two-day event for the e-commerce behemoth Amazon (AMZN Quick QuoteAMZN - Free Report) . Online sales surged 6.1% year over year to $11 billion in the 48-hour shopping event, topping the record $10.9 billion in e-commerce spending on Cyber Monday in 2020, according to Adobe.

Monday was the biggest day with $5.6 billion in digital sales, followed by $5.4 billion on Tuesday and was driven by strong demand for online shopping as consumers look forward to a return to normalcy. Per CNBC, the Adobe report stated that “the halo effect of Prime Day also played a significant role, giving both large and small online retailers significant revenue lifts.”

Big retailers with more than $1 billion in annual revenues saw a 29% jump in e-commerce sales during the Prime Day while smaller retailers with less than $10 million in annual revenues saw a 21% increase. According to Digital Commerce 360, e-commerce sales spiked 7.6% to $11.19 billion during the two-day shopping event (read: ETFs to Buy on Strong 2021 Retail Sales Outlook).

A record number of Prime members shopped for more than 250 million products worldwide during the event. The best-selling categories worldwide were tools, beauty, nutrition, baby care, electronics including Amazon Devices, apparel, and household products. In fact, Fire TV Stick 4K with Alexa Voice Remote was the hottest device this Prime Day. Additionally, Amazon Fire tablets and Fire Kids tablets, including the all-new Fire HD 10 tablet, Fire HD 8 tablet, and Fire HD 8 Kids tablet were also popular.

The top-selling products include iRobot Roomba 692 Robot Vacuum, Keurig K-Slim Coffee Maker, Apple Cider Vinegar Gummy Vitamins by Goli Nutrition, and Crest 3D White Professional Effects Whitestrips.
