Commission Junction
I was updating some of my web pages and found out that buy.com had lower prices on some items than Amazon. Sometimes the difference was pretty significant so I thought it wouldn't be right to avoid linking to buy.com just because I get a commission at Amazon. But of course that made me wonder if buy.com had an affiliate program. Turns out they do, but they run it through a third party called Commission Junction. That company has a bunch of other advertisers as well, so you can promote all kinds of different things, but the commissions are lower (3%) than Amazon. I decided to sign up since it is free anyway.
The sign-up was kind of a pain. I had to agree to three different screens of terms and conditions. I don't think I had anything like that with Amazon. So right off I was a little put out with them. I only link to about three things at buy.com and they aren't the big sellers that I link to Amazon, so the bottom line is I have only gotten a handful of clicks and no purchases so far. During the same period Amazon has been pretty slack as well, so I will give them a couple of more weeks, but if it doesn't look like I'm going to make much of anything I think I will get out of the program and link to buy.com products anyway.
