Do you guys have an experience with coupon sites? Do you know where to get these offers? CJ? Other affiliates?
Yes, CJ seems to have the most good coupon offers. You can search for merchants that have coupon-type links listed. (Not all of them turn out to be real coupons, but that's another story.) I have a coupon site that's populated mostly with CJ stuff. It makes me an occasional $20 here and there. Nothing big. It would probably do much better if I kept it up to date with new and current offers, but I find that's an enormous amount of work.
