Be aware that gift cards should only be purchased at locations that sell them behind a counter. It is a common scam when retailers place the racks of cards out in the open for people to take a bunch of the cards and remove the grey scratch off tab and copy down the code. They will also scratch off a couple of the numbers to give them more time to use the card after it has been activated. The grey stickers can be purchased from Amazon and they will then just cover the code back up and return the cards to the racks open to the public. After you activate the card, they can use them before you get a chance to. Retailers have known about this scam for years and the ones that care about their customers will not leave them out in the open.

I find it odd that those same retailers will lock up Baby Formula, Cigarettes, and Cold Medicine to prevent them from losing money, but when it comes to their customers losing money to the most common gift card scam, they just don't care.
