Makes for great gifts
Bought this during some type of promo.  10 cards lets you hand them out to people as gifts.  Great for secret santa party for example.  All worked and can be added to same account.  Not easy to see your balance from Amazon home screen.  Requires too many clicks.  The process to reveal the codes requires rubbing off security part on the back of each card.  Some codes are pretty lightly printed.
