Just be careful.. I've heard too many stories of people having their credit report pulled just because they took a car for a test drive and the dealer asked to get a copy of their license first.. (I think this is ridiculous, personally.)
Hard inquiries have a dollar value to some people, so if they do to YOU, be sure you are getting a gift card with a value that makes it worth a possible hard pull.
I have told my husband in the past, regarding other credit issues, "if its only going to save me $100, forget it - it's not worth an Experian pull" ... but YMMV of course!
