I only got into this as someone gave me a $150 gift card. After all sorts of run-around trying to pick wines and use the gift card, turns out that you have to give them your credit card info, even when you have money left in the gift card. I might have done it (1) I wasn't so irritated already and (2) I had my purse with me. The swapping out process is very limited, there are no prices disclosed at any point during the process.
