A while back Cuong and I signed up for a website called Swag Bucks. It's a super easy way to earn free gift certificates, etc. All you do is use it as a search engine for everyday things. We have it set as our homepage and use it to search for things like, "hotmail" or "google mail", or anything else. It will show you the link and every so often you earn a "swag buck". Since we've set it as our homepage we've been earning them really quickly.
We've been using it since Halloween and we've already received $45 in free Amazon gift cards.
There's nothing to install, no commitment!
They have a store full of things that you can cash in your swag bucks for.
Click the link and sign up...start earning some awesome free stuff!
