Prime Day 2025 was a treasure trove for Stanley lovers. We saw the brand's viral 40-ounce tumbler on sale for its lowest price ever, or 44% off. And even though Prime Day deals are winding down, you can still save on top-tested drinkware in select colors and sizes.
At the Good Housekeeping Institute Kitchen Appliances and Innovation Lab, our experts have rigorously tested Stanley tumblers, water bottles and coolers — and it's safe to say, we're big fans. The iconic Stanley Quencher H2.0 Flowstate Tumbler is perfect for a day at the beach this summer or long road trips to your next vacay. Only two colors are still on sale at Amazon, a vibrant orange and a deep plum — but we spotted a few steeper discounts and more colorways on Stanley's website. Ahead, find last-minute deals from Stanley for Prime Day 2025, including discounts on tumblers, coolers and more.

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 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.
