I know you can earn gc's for Amazon thru SwagBucks. But what I wanted to ask is what other programs are out there that a person can do to earn Amazon Giftcards? I know there was a place some yrs back I think gave you one for reviewing products but I don't recall what that was. Any suggestions of sites / programs that you can earn that way would be appreciated.
