I have used ChannelAdvisor. I found it really lacking. It was excellent for pushing out postings, but when your employee makes an error, we had to fix everything by hand. Also we were selling in Ebay Motors, which ChannelAdvisor did not handle as well as the normal Ebay. And then Channel Advisor took another 2% cut on top of Ebay fees, paypal fees. Too much money for not enough benefit was the reason I stopped using it.
