It's called Swagbucks. I resisted at first but it just makes sense. I have two friends who have both received $100 or more in gift cards just for using this as their search engine.
I love google.
I am loyal to google.
The good news is... swagbucks is a part of google! sigh
So, go and register and tell them I sent you and then go to Heather Hendrick's blog (like in my blog roll) and comment on her blog that you signed up and that I told you to and we will both be entered to win a $20 Target gift card.
Further incentive: their gift cards that you can win include Southwest Airlines, REI, Target, Lowes, Fandango.... GO!
