So I actually came to this site before I signed up for the offer.
I onestly thought it was a scam, but ~30-40 days later, my check for 20.95 (2 offers) came back! Boy am I surprised!
I was given a 1-month trial of it and it said I would be charged afterwards if I continued the service.
Here's what I did.
I used one of those visa gift cards worth just $25, and I signed up with that as my payment card, and I believe it was never charged.
After about day 25, I thought the check wasn't coming, so I unsubscribed thinking no harm done.
Well I surely benefited from trying! I might sign up again if I ever am buying large amounts of things on the internet in which they support your rebates!
Definitely worth a try!
JUST REMEMBER: Unsubscribe before a month so you aren't charged!
