Yes, it will work just fine. For those who shop often at Costco, keep in mind that Costco offers its own cash cards (which can be purchased from costco.com - using Visa, Mastercard, or American Express credit cards). This is a quick and easy way to cover spending requirements for credit card bonus miles/points. But note: "You must be a Costco member to purchase...Costco Cash Cards." However: "Members and non-members may use the cash cards to shop at any Costco location or at costco.com."
