Do what everybody else does and setup numerous eBay accounts. More to manage but cost can be kept lower.
Thats an interesting idea, but wouldn't that just lead me to the same problem, we are currently spending a few hundred pounds on fees, its a good idea, i feel that this would spread my fees out, but still amount to the same money overall.
If u want your own site as a biz card or even storefront, you can do paypal buttons or link back to ebay. This would keep your web dev and maintenance demands down. Depending on traffic, google adsence may be some added revenue
Okay, this might be useful, would i still go to one of the mentioned websites and build the page as i was maybe going to, i mean ideally i would like to get away from eBay as the fees are getting very high. I also guess that i can list on my page the items, and as you said i could just include the paypal button, which is what we do on facebook, i will look into this a little further. But any more suggestions please keep them coming.
