Perhaps you you should entertain offers when posting chips for sale? I'm sure you'll get lowball offers but you always reserve the right to decline. I guess it's a buys market right now given that demand seems to be very low. In your case you may have to sell cheaper but you should also be able to buy chips cheaper too. I've purchased many chips (admittedly nothing really high-end) from board members, Marlow and All Chips but never on eBay. I don't like auctions I guess.

Good luck hopefully things will improve!
