I'm quite new to selling on eBay so still finding my feet. I've got an item on there at the moment, which has another 5 days left to run. It's got 6 watchers and 9 bids so far. I've seen the same item sell quite frequently, generally for between £45 - 70. Put it on at 99p, no reserve and no BIN price. Someone has messaged me asking whether I have a BIN price. I thought that I can't add one once people have started bidding, is that true? I think I'd rather just leave the auction to run but not sure if that's the best thing to do. Any advice?
