You heard us, f-o-r-t-y percent off, meaning you can grab a brand new, mega-viral tumble starting at an unheard of $21. The lowest price we’ve seen them at, ever. So you better act fast. Lest we forget, the Stanley Quencher is break-the-Internet famous. Just a few years ago, the cup boasted a 150,000-person waitlist. So if you’re thinking about finally getting one (or finally getting another) — now would be the time.

The Quencher’s unstoppable popularity came as a surprise to the heritage drinkware brand.

According to the New York Times, Stanley discontinued the cup in 2019, assuming their mostly male customer base wasn’t interested. When a trio of parenting bloggers noticed a wave of their female readers loving the cup, they campaigned for Stanley to bring the Quencher back, creating a loyal women-led fanbase.

“The Stanley Quencher success story is one of our brand listening to women for incredible results,” Terence Reilly, global president of Stanley previously told HuffPost. “The Quencher’s popularity comes from listening to female consumers and providing them with the colors, innovation, durability and style they covet.”

There’s no telling how fast these beloved cups will sell out (a few discounts actually vanished while we were putting this story together) so move quickly to nab this first-time deal.
