V7N

The V7N affiliate program pays you for every sale made of a link in the V7N Directory. The payout rate is $25 per sale. You will also earn from the sales of affiliates you refer to the program.

So far, I've received $250 in commissions from them paid to my PayPal account. No sales in a while though. I also have four downline members, but no commissions generated from them as yet.

Still, $250 isn't bad for totally passive advertising.
