Swagbucks is a fun way to earn $5 Amazon gift cards. Just sign up here, install the toolbar and use it as your search engine (or one of your search engines :). I use it a few times a day and earn 1-3 Swagbucks on average. Took me about a month to earn 45 which you can redeem for a $5 gift card. You can also save up and redeem for TONS of other things. Anyway, fun way to earn a buck :)
Some people save them up till the end of year and use them to get Christmas Presents. Good idea!!
