I bought an NFL shirt a while back form a seller in Hong Kong and they sent the wrong size.
Ebay then binned the seller, as they suspected it was a counterfeit operation (Football shirts from Hong Kong and about a third the price you'd pay over here - no shit, Ebay!), which left me with a brand new shirt, I couldn't return or get refund for.
So I decided to sell it.
The minimum reserve I could put on it was £50 (having paid only £28 for it myself), so I was left with the choice between putting a ridiculous reserve on it and it not selling, or going without a reserve and having to let it go for about three quid....
Needless to say, I've still got it so if anybody wants a brand new, (ahem!) Nike Washington Redskins RG3 jersey in Large, complete with tags, PM me and you can have it for 25 quid.
