Stumble Upon is doing a really cool promotion. Stumble Upon is actually pretty cool. You tell it what you are interested in and it basically helps you to "stumble upon" super cool stuff that you'd be interested in. I just found an awesome new way to braid my hair. Who knew?
Anyway, if you sign up for Stumble Upon (or if you're already a member) and get some friends to sign up, you'll get free Amazon gift cards. For every 5 people who sign up under you, you will get $10! Wow!
Here's how it works:
Step 1: Sign up for Stumble Upon here.
Step 2: Sign up for the Amazon promotion here.
Step 3: Share your link with friends (it also has a facebook share button)
Step 4: Earn amazon gift cards, buy super cool stuff.
