I can see the buyers point too, and I'm afraid I agree with both Bruno and Gugi.

A comma inserted in a sentence can completely alter it's meaning, that's obvious. An extreme example I saw online recently is "Rachel likes cooking her family and her dog" - insert a comma and the meaning changes: "Rachel likes cooking, her family and her dog"!

However, the hone-wear is pretty self-evident in the picture and as the picture is an inherent part of the listing the buyer should have been aware of it.
