While you can’t order an ice cream float at Costco’s food court, you can craft yourself one by buying a cup of ice cream filled three quarters of the way full and a soda you like.

Simply pour small amounts of soda into your ice cream as you eat. At $1.99 for the ice cream and 69 cents for the soda, the float will cost you less than $3.00 (before tax).

If you're not a fan of vanilla, you can order a cup of chocolate ice cream for no extra charge. You can also buy a sundae for your float, but the sundae alone will cost you $2.49.

You can choose from various ice cream and soda pairings, but Costco food courts only serve Pepsi products, so a Pepsi float will be your closest bet to recreating a Coke float.
