What is Swagbucks? Swagbucks is an awesome site that lets you earn points which you can use to redeem for giftcards or various merchandise. I typically redeem for amazon.ca giftcodes (you only need 450 swagbucks, which takes about a week to earn). I have earned $10 for Home Depot and $275 for amazon since September 2011! Sure it's not a fortune, but it certainly helps when it comes to giving gifts!
The amazon codes you can redeem for are simply a alphanumerical code and many people will trade coupons for the codes (expect about $50 in coupons in exchange for a $5 code) - certainly a good way to get your hands on some much wanted coupons!
