Swagbucks is one of my favorite sites! I have earned over $450 with Swagbucks (Amazon and Southwest gift certificates). It is easy to use. I use the search engine to get most of my points, but you can also shop, trade in (video games, old cell phones, etc) items, or type in codes to get extra bucks.
You can trade these points in for gift cards, video games, musical instruments, books, and so much more! I use my points for Southwest gift cards!
Now through Tuesday June 16th you can use the code HEIDISCODE (case sensitive) when you sign up to get 6 points! Just go to Swagbucks and enter the code when you sign up.
