Stanley Cup Plummets to $20 During Amazon Prime Day 2026

Stanley delivered on its Amazon Prime Day 2026 deals. The water bottle and tumbler retailer majorly slashed the prices on some its most iconic cups in its most coveted colorways, including a $20 tumbler.

• Classic Stanley cup on sale: See here

While we wish we could say the whole Stanley Amazon storefront is on sale, only a selection of hydration essentials are. But, they come in both 30-ounce and 40-ounce options, plus they’re available in a variety of fun, bright colors and eye-catching patterns that make staying hydrated feel a little more exciting.

We have a feeling these deals won’t stay in stock, so you’d better grab your favorite color fast.

Even if you’re less into the shade “violet blossom,” you can score Stanley tumblers in gunmetal, citron, creamsicle, and so many more. Plus, these deals apply to classic Quencher H2.0 Tumblers and Quencher ProTour Flip Straw Tumblers.
