It does sound like he's threatening you.I saw $12 shipping on a tie once and didn't buy it because of that. I think $10 is pushing it, to be honest. I ship all ties first class mail, except my more expensive ties, which go into a small flat rate box. Spend a lot of money = get package faster. I would do the same if someone bought a $150 dress shirt, for example. Normally I would ship the dress shirt first class mail, but would upgrade to priority for a large purchase.
