Yeah, I did something through some site for a $50 mastercard... had to do something (I forget what, but no referrals). Got it, but email was spammed.. so I have a dedicated email for these things now. Then I signed up at
www.offers4free.com and have gotten paid around $100 through them. I had to sign up for Stamps.com (which costed like $1 or $5 or something) and Netflix (which I ended up keeping because I liked it so much) then Blockbuster Online (which I switched to after Netflix... because it's better). They both costed like $10 as a promotional trial membership.
Anyways, this one was tricky and took a long time, but in the end I guess it was worth it.
