I write no returns in my eBay auctions just for this reason. It is becoming very common for people to just look at pics and click buy and then when they ordered the wrong thing due to impatience and pure stupidity it is automatically the sellers fault for not saying "Are you sure, yes or no?" .
This guy does sound like pro though, and well educated. After all he didn't just start playing yesterday, he must be a grizzled veteran and they are never ever ever wrong.
