DO NOT BUY AMAZON GIFT CARDS
I recently bought 10 $20 gift cards but was informed that there was an error so they reshipped me 10 $20 ones. I got confused which ones are valid so I was trying to check balance. After spending about one hour to figure it out myself, I called Amazon - the representative spent 1.5 hours and put me on hold a few times and couldn't figure it out. I was told the only way to check is to redeem it and once you redeem it, you can't get a refund anymore. This is horrible.  I tried to file a complaint but the representative hang up on me.
