I've put two guitars on eBay in the past ten days, one sold 'cleanly', and profitability in a five day auction, and was shipped out yesterday to.it's new owner. The second guitar is a different matter, however. It was posted in a seven day auction, and was sold to a person who payed for it immediately via PayPal. A few hours after it closed, he messaged me and said that if I would like to cancel the deal it would be ok with him. I sensed that he was experiencing a dose of buyer's regret, and I didn't want to ship, and risk, the guitar only to have him regret his purchase and perhaps pursue a refund later. I just returned his money, and relisted the guitar, this time in a five day auction. It was bid on and won yesterday by a guy who had only been on eBay since January 20th, and had only one previous eBay transaction. BIG 'red flag' there. This ain't my first rodeo with this kind of thing, but I would give him the benefit of the doubt and see how it would go. It's been over twenty-four hours now, and no payment, and no communication as to his intentions. I've now messaged him twice to ask if he still intended to pay for the guitar, and that I would relist it AGAIN tomorrow (Thursday) if he didn't at least respond to my communications. I've been buying and selling things on eBay for about twenty years, and have only had any difficulty with a buyer one or two times out of over 200 transactions, and those were resolved quickly and amiably. The guitar I'm selling is virtually new and unplayed, and includes a fitted hardcase, for less than half the price of a similar new example. It will almost certainly sell (again) in its third auction, but this is turning into a bit of an exasperating experience at this point, and I really wish some people wouldn't commit to buying these things if they're not certain that they really want it.
