Number 1: Lots of People already signed up for these sites
Number 2: How do we know your gonna pay us?
- Why don't you give us $5 now and $5 later, or is $5 too much for you? If it is, then how can we trust your gonna give us $10!?
Number 3: It costs more than $10 for a offer sometimes, Your only paying $10 so their not making much money, if at all, losing some.
- Not worth our time to work for a hour, ordering service and then cancelling for a few dollars or losing money at all
Number 4: you can only earn 1 gift
I sugest freetechshop.com, because you can have multiple gifts! My referral link is 4!
