Your new favorite summer snack has just hit clubs nationwide.

We love big-box stores like Sam’s Club and Costco for so many reasons. For starters, you can get a great bang for your buck and snag healthy groceries for a fraction of the price. But there are also some hard-to-find things you can get at these stores, and often for short time period—like cotton candy grapes!

We love these super-sweet green grapes for their spot-on cotton candy flavor. Plus, there are no artificial flavors or genetic engineering—the sustainably grown fruit gets its flavor from a specific type of plant breeding! Crazy, right?

Cotton candy grapes are a perfect sweet treat for when you’re trying to eat a little healthier and don’t want to turn to a sugary, packaged dessert. But if you’re like us and love these unique grapes, you need to run to your local Sam’s Club ASAP because they’ll only be in clubs for the next three weeks or so! The grapes come in 3-pound plastic containers, so you can enjoy their spun-sugar flavor for days on end.

Not a Sam’s member, but want to get your hands on some cotton candy grapes? We’ve got a hack for that, too.
