Just got an email from CafePress stating that they will discontinue their affiliate program and they will migrate their system to Commission Junction. Here is a quote from their mail :

About a year ago we launched the CafePress Affiliate Program. We saw it as a revolutionary program with benefits for Shopkeepers, Affiliates, and CafePress. As you know, the basic purpose of an affiliate program is to drive incremental external web traffic – and ultimately sales. Unfortunately this program did not meet that key objective, and a continued investment in a program that was not meeting this basic goal became difficult. Ultimately this program lacked ability to scale, build momentum, and ROI.

Looks like CafePress’s affiliate program was not a success, and I guess that wont change when they’ll migrate with CJ as webmasters need more options regarding advertising, and CP’s affiliate program don’t give many of them. After all CafePress is more useful as a company to create merchandise for your site, than an affiliate source of income.
