So far we've had only two publishers sign up ... and I'm one of them. :-)
The tools for publishers are still a little coarse, but the web site allows you to build links to categories or specific products. And it provides a web service for getting category and product info in XML.
do you have an affil datafeed for your products, a la CJ?
I have a kite site but I think the company I made it for is fading slowly. (bonuses for four months this year haven't showed up, the person in charge says he's been very sick recently, no real communication)
We're about out of the season here, now. Time to consider changing the theme slightly to "outdoor" things to do. I've built the pages using popshops, but have webmerge so a datafeed would work.
