To be honest its not that difficult to sell direct on ebay…they do make things pretty simple! It’s probalby best to do this and set up some kind of ‘ebay store’ which ebay allows you to do.
I sell on eBay and I also use the Auction Suite. In the beginning, I used eBay’s listing services, but the free one is ugly and the styled ones cost money. Plus, you are still locked into their templates, and isn’t that one of the reasons you are using Freeway? So you don’t have to be locked into a template?
