If I have an idea of the price and value, yes. I'd rather just pay a little more and get what I want, without the waiting, sniping or bidding.

Listing things, If I don't know, I might try an auction.

One thing that I didn't do before and I use with mixed interest is allowing the make an offer. Especially if it's something that hasn't sold after a couple tries, and has watchers. The down side is absurd low offers. But I suppose if someone is working at "buy and sell" and they can grab an item for well below the usual, they have to give it a try?

Good that you brought this up, I might do more BIN as a seller.

NCR I'm selling a Marilyn Monroe slide collection, people look, but no bids. https://www.ebay.com/itm/126036512165 I think there's much less interest than I had expected.
