Hey, I've just started selling and with 7 days to go, I got a question from a potential buyer asking me to set a BIN. I don't think I want to set one and would rather have the auction run its course. How do you say no delicately? Or would you ask them how much they'd be willing to pay for the item? I don't really know how much I want but woud like to handle this correctly and not lose a bidder if I say no to the BIN. Thanks in advance!
