As some on who works in design in the apparel industry, I can tell you that labels, packaging and zippers all change frequently from season to season. Even when styles are repeated, as in basic stock replenishment programs, new packaging is often developed for no other reason then to keep the designer interested in what he's working on. Furthermore, grammatical mistakes on labels are far more frequent than you would think as well. While I was working there, Rugby ran a label that said "Rubgy" on it for two seasons without anyone catching on.
Check Chestercopperpot's previous feedback, its perfect. He sells so much on this site. Why would he risk his impeccable SF seller's reputation, one that has taken him years to build, for a couple hundred bucks? Think about that.
His only mistake has been to give in to you vultures and issue a partial refund at all.
