Quoted from AlexF:I once held 3 backglasses for a guy for 2 and a half years. He paid up front but never could justify the trip to come down to get them. I finally relisted them and it inspired him to come get them. He was kind of pissed that I had the audacity to relist them.
It should be after 2 1/2 years the buyer had the audacity to believe you still had the glasses!
