I returned some items to BR which were originally paid for with a Visa gift card. Instead of getting cash back, the money went back to the gift card which I had promptly tossed when The balance was depleted. BR is trying to help but I am not optimistic.

You all probably follow these rules but here goes:
1. Ideally use gift cards for purchases that don't have to be returned i.e. gas, meals

2. If you buy something that needs to be returned, save the gift card.

3. It is best to register the gift card if it has a large balance.

Update: Situation happily resolved by BR customer service. Visa was a pain to deal with but BR was able to reverse the transaction (or eat the loss, not sure which) and issue me a BR gift card which is what is supposed to be their normal procedure.
