Amazon's Prime Day expands to four days with millions of deals

Amazon’s four-day Prime Day ran June 23-26 with millions of deals across more than 35 categories, and the most useful budget buys were the seasonal basics Amazon itself highlighted: swimsuits starting at $8, suncare essentials at $7, and curated summer, travel, and dorm-room items. For shoppers trying to stretch cash, those are the listings most likely to deliver real value because they cover needs people will actually use after the sale ends.

Prime Day has become a much larger fixture than the one-day event Amazon launched in 2015. The company stretched it to two days in 2019 and, by 2025 and 2026, had expanded it to four days, with millions of deals and more than 35 categories spanning clothing, beauty, kitchen, home, electronics, groceries, patio furniture, and back-to-school goods. Amazon also pushed curated Top 100+ lists and said deals could refresh throughout the event, reinforcing how aggressively it used the sale to steer shoppers toward a narrow set of seasonal bargains.

The cheapest listings deserve the most skepticism because Amazon’s marketplace relies heavily on outside sellers. Amazon says more than 60% of sales in its store come from independent sellers, while marketplace trackers put third-party sellers at about 61% to 62% of paid units sold, a share that has made the bargain bin especially crowded with small and obscure brands. That is where many under-$25 gadgets live, and the low price often comes with weaker quality control, thinner warranties, and listings that are harder to evaluate than items sold directly by Amazon.

The review problem is not abstract. The Federal Trade Commission’s consumer reviews rule took effect on October 21, 2024, banning the sale or purchase of fake reviews and allowing civil penalties for knowing violations. Amazon said on July 31, 2025, that it and the Better Business Bureau had filed a joint lawsuit against fake review brokers, signaling how much of Prime Day shopping still depends on separating genuine discounts from listings padded by deceptive ratings.
