A company, appropriately named Shottys, makes pre-made jello shots and they're waiting for you at Costco!
Shottys comes in a variety of flavors like Lime and Orange. However, Costco is currently offering them in a 24-pack that includes strawberry, blue raspberry, grape, and watermelon.
Each shot is made with real vodka and contains 12.5 percent ABV. (Mashable)
