A great way to save on airfare! Using $200 gift cards allows you to book airfare saving a some dollars thanks to the discount offered by Sam's Club. You are allowed to use a total of three forms of payment, gift card, credit, or debit. By booking each way separately, I was able to pay the round trip airfare for three people using the gift cards and one other form of payment. These gift cards were delivered electronically, and arrived within a couple of hours time. The gift card numbers with their included PIN number, can be used immediately.
