"What I do get about this"? This a get. Because I am new to this forum, there is a time lag between when I post on item and when it actually gets posted. The problem is in your previous posts posts you stated that basically he was being ungrateful, because he bought this shirt, and other shirts from you in the past cheap. You were implying that he should have overlooked this stain and not complained. If you stated this defect in your listing then politely tell him to reread the listing and that the stain was clearly stated.
A similar situation happened to me in the past. I bought a sport jacket very cheap. Upon receiving it, I noticed that there was a stain on the sleeves. I checked the photos in original listing and noticed that under the zoom you could clearly see these stains. I did not contact the seller. I took the jacket to the dry cleaners, he cleaned the stain, and that was the end of the story. I think I was a very reasonable and good buyer. I did not try and weasel any money out of him. I would hate to think if the stain did not come out, and then contacted the seller, he would have refused any resolution because the jacket "was not in its original state".
That isn't what I said at all. I offered him dry cleaning money and a discount, but that doesn't mean I still do not think he is trying to cheat me. If I received something with a stain, I wouldn't try to clean it multiple times prior to contacting the seller. I would contact the seller telling him that he did not describe the item properly and wait for him to contact me with instructions. Merry xmas.
