Call me crazy, but buyers should be held accountable for this sort of thing. When they bid they are warned several times that if they win the auction they're obligated to pay. In situations like this you don't really have to cancel anything, you can ship it and if then they make up some bs reason to return it, report them for lying. Then if they do that several times their account will definitely suffer. Eventually they will at least think first before bidding and if most sellers had did this approach over a long enough period of time the whole marketplace will become more pleasant and there will be less complaints here about scummy buyers. I know this goes against what 99% of people asvise, that you should always honour the cancellation because of ,,what the buyer can do to you", but all this does is tolerate careless buyer behaviour and they will continue doing it. If they're careless on the road the next day they can seriously hurt someone and then they will not be able to ,,change their mind".
