Thinking about giving a fancy new gadget as a gift? Or maybe there’s something on your wish list? If so, you might be tempted by an ad for high-tech at a low price.

In fact, Amazon’s gift card terms don’t allow you to use Amazon gift cards to make payments anywhere besides amazon.com and a few specific sites.
