Happy Prime Big Deal Days to all who celebrate! Amazon's October Prime Day is here, and the sales are good. I mean, have you seen the fashion deals, beauty finds, and markdowns on AirPods and other Apple products?? It's almost as if the e-comm gods know me. All my favorite things are on sale—including tons of Stanley 1913 tumblers.

We're talking up to 40% off IceFlow flip-straw tumblers, 30- and 40-ounce FlowState Quenchers, and more emotional support water bottles than your cabinets could ever have space to hold. The only catch? The clock is ticking if you actually want to snag one before they're back to full price. ICYMI, Amazon's Big Deals Days is coming to an end tonight at 11:59 pm PT. The cups have also been selling out practically before my eyes. Do with that info what you will!

Take the IceFlow Flip Straw Tumbler, which (if you don't already own one) is a must-have. The 30-ounce design is just $21 right now (a steal) and will keep your bevvy chilled for up to 12 hours and iced up for two days. It's vacuum-insulated, leakproof, dishwasher safe, and so easy to carry around with that top handle. It's my fave Stanley for that reason.

Of course, there's also the cult-favorite: aka the Quencher H2.0 Tumbler. It comes in practically every color, so really, you can never have enough. Maybe you need a Stanley for every day of the week or every room in your house. Convenience is priceless, besties! Remember that!

Several of the 30-, 40-, and 64-ounce sizes are marked down and offer the same perks. It has a rotating lid with three positions, including a straw opening to resist splashes and a seal that holds the reusable straw in place, a drink opening, and a full-cover so you can avoid leaks altogether. Oh, and the handle? It's ergonomic with a comfort grip that's easy to cart around. Ya know, in case you don't buy one for every room in your house.
