October Prime Day—which comes to a close tonight!— is one of the best times to snag a Stanley product (or a couple). Why? Because we're seeing significant savings right now—and we're personally big fans. The viral water bottles and tumblers have been praised for temperature retention and durability by the Good Housekeeping Institute.
Whether you're looking for a new tumbler, a bottle to insulate your beverages, or a cooler to keep your favorite drinks and snacks chilly, you won't want to miss out on heading over to Amazon and adding a few to your cart before they sell out.

Are Prime Day Stanley deals worth shopping?
Yes, we would recommend tumblers, water bottles, and coolers from Stanley even at their full prices—and since the brand barely hosts sales, we think these deals are worth the purchase. Our pros tested the Stanley Quencher Tumbler and appreciated how much water it held (40 oz), despite being comparable in size to a 30-oz tumbler. Plus, the large handle and tapered base makes it easy to hold and put into car cup holders.
Additionally, the Stanley IceFlow Stainless Steel Tumbler (which is currently 40% off) is our experts' favorite tumbler for traveling, thanks to its leakproof straw and tapered bottom that fits most cup holder. Plus, the All Day Julienne Mini Soft Cooler cooler from Stanley was even a winner of our Kitchen Gear Awards last year.
Does Stanley usually participate in Prime Day deals?
Historically, Stanley has participated in major sales events like Amazon Prime Day or Black Friday, but would never include the popular Adventure Quencher tumbler as part of their sales—that is, until recent months. In early 2025, we noticed the brand slowly started promoting discounts on the tumbler both on Stanley1913.com and on their Amazon storefront.
Note that the brand isn't always generous with their promotional offerings—and when they do share discounts, not all colors and models go on sale. So when you see a discount, we think it's worth the purchase.
What are the best Stanley cup alternatives?
Our Lab pros have tested so many Stanley alternatives in the GH Institute, including picks from brands like Owala, YETI and SimpleModern—and a few of them are still on sale for Prime Day.
