Gah! eBay buyers!
For this listing:
Funny that I have a picture of the collar in there and no wear.
I am sorry this happened to you man.
While it is buyer responsibility to look at measurements, I feel that many pay lip service to these and go by size tag or inferred size tag (most have no clue about their measurements).
The suit measurements you posted indicate a trimmer 46R or certainly a bigger than average 44R (with 48US shoulders). Still though, stupid buyer for not checking measurements
Suit probably did not fit the buyer well, and he is throwing as many random excuses to make sure he gets his money back.
I also hate how many buyers think that a private seller is somehow a Neiman Marcus. They do not realize that their stupid mistakes cost sellers money through eBay fees and postage (a full refund includes eBay total with postage to buyer so seller picks up this tab). I too would like to know the ID of this buyer since I could well live without those that think it is OK to return something on a whim (or if they make an error, the seller must pay for it).
