Oh well. I don't sell my guitars on eBay so others can be entertained.
I just sold two guitars - one auction, one best-offer. At one point I had 25 watchers on the auction. Nobody bid until the last three seconds, so the opening bid won it. Glad I set a decent starting amount.
On the other, the BIN price was about a hundred fifty more than I thought I'd get, so I took the first offer that came in $75 under.
After you pay the listing fees and the PayPal fees, you don't clear all that much, so I take no chances.
Yeah well the boring way you run your stuff, I don't think you have anything to worry about.
