I did one with Amazon, beyond, and NextCard once for about 18 months. Although my site was very busy, I didn't make much money. Fortunately I wasn't paying to host the site so it didn't cost me, I mention this just in case you pay for your own bandwidth because if you exceed it, it could end up costing you. I also felt that they were getting free advertising from me, and I wasn't really getting anything from them, so I dropped it. I haven't done one since. However, that was just my experience I do know of those who have profitted quite well from it. I suppose you could just try it out and see how it goes, you can always stop if you don't feel you're getting anything out of it.
That's right Mike, you can always stop. But you may also find you are chased down via email for the rest of your life.
We, as a host, prefer to work through 'reseller' set ups. It's much easier to control. Much cleaner for all involved. We sell to you, you then sell it on to others. Whatever profit you want you tack on as mark up. You can make a lot of money this way.
Referrals are a good easy way but, as you said, you wouldn't wanna be paying for all the extra bandwidth.
Thanks for the sound advice, Benno and Mike. I guess I'll try a few out to see how it works and if it's worth any extra work I might have to do.
Michele - Thanks for the link, I haven't had time to check out the referral offer quite yet. I'll be sure to look it over and give you any feedback. I am new to this whole thing, so my basis for comparision is quite limited.
