Revat raises good points. I would like to reiterate that the Boards are not ebay, your books won’t get as many eyes. I do like selling here, but many times I’ve had no bites and then quickly sold the books at higher prices on ebay.
Be prepared for lowballers, and lowballers with sob stories.
Best to think of the marketplace place as an additional venue for selling as opposed to an all-out alternative to ebay.
Finally, while I’d prefer not to pay it, 10% in fees is pretty minuscule to get your goods in front of thousands of potential buyers. You’re not likely to find a source to consign books for less than that.
What kind of books are you selling? Do you have anything up on ebay right now?
