Is there a service out there (with an affiliate program) that provides an online escrow service for the transaction of goods between my site's members? I have a "For Sale" section on my automotive message board for people to sell their used or no longer needed parts. On occasion people are victims of fraud. I was hoping I could find an escrow service that can handle the completion of such transactions and could also generate revenue as an affiliate for sending business their way. Of course, this would be optional to the user but I still want to be able to offer a service such as this while also heling to generate revenue as a result. We suggest iescrow.com (now Tradenable) but to my knowledge, they do not have an affiliate program that actually pays out revenue.
I am considering running a contest where people have to sign up for a free online service in order to enter the contest to win free merchandise. We did this last year by having people sign up for a free Photopoint account (through their affiliate program) and forward us the account confirmation e-mail as an entry to the contest. Then we selected a random e-mail as the winner of the contest. It worked reasonably well, but many already had a Photopoint account and the payout wasn't all that great.
Is there a better way of doing this while not being very obtrusive to the potential contestant, providing a free service or product and sending a decent amount of revenue in our direction to pay for the merchandise we are giving away?
Thanks in advance for any advice!
