Yeah, I hate Fees on eBay, shipping has never bothered me; but mostly i haven't done much of any kind of business on eBay because everything costs too much i don't find it worth my time unless i can sell things at a certain price or higher; and then you have "Nightmare Customers", which is to say people that seem like normal customers; until they make up some excuse to try getting a refund.
I do from time to time sell some diapers if I ever overstock in some way, shape, or form, particularly if I need money.
If you could sell things on a community website like this you could avoid eBay fees at least, but the bad thing would be a smaller base of potential customers.
Either way, selling things on eBay is rough business and I hope it all goes well.
