I’ve had similar experiences. My latest was a bidder who won, waited three days to respond on winning. Called me to say it was a mistake and could I throw in some free items which was weird. Then I waited three weeks with no payment and several attempts to make contact with no luck. I then sold it and the payment arrived the next day.

I am currently fighting GB on the fees due to the delay in payment but they’re hard to get to respond. I felt bad at first thinking the mail was slow but then realized it was postmarked a week after he called me causing the delay. Between all that and two guns “growing legs and walking off” from a UPS hub in TN I am done shipping for a while.
