The Daily Meal has been keeping tabs on the comings and goings of Costco bargains, so if you're looking for some cool drinks, a handy machine that makes frozen treats, party supplies, and more, keep reading.

Some of the deals end soon, so if anything catches your eye, it's best to pick it up now. Only one deal on our list of savings on kitchen appliances at Costco is still active (check it out if you're still looking for a new freezer!). Keep in mind that prices and availability vary across regions. The costs listed below are the typical prices — your Costco may be cheaper or more expensive. Prices on alcohol will have the biggest variance, which depends on your state's liquor laws and taxes.

Oat milk is one of the creamier plant-based options for those avoiding dairy. Great for morning cereal, to pour into your morning cup of coffee, or drinking on its own. Oatly Original Oat Milk comes in a pack of three for $11.99, but is $3 off until June 28.

This summer looks to be an especially hot one, so prepare to hydrate with a case of coconut water.
