Great that you are going to check it out. Don't wear a watch and drive a beat up vectra, at least you can't get robbed.
The whole thing just is weird. The box obviously looks good. The tins and containers seem ok. The paperwork, stella paper, etc etc all looks original. So how does a 62 feedback clueless seller end up with this stuff??!! Perhaps someone was up to no good, gave up, sold it at a flea market for 5 quid ? Idunno... Just really really WEIRD.
