Glove Shipping Etiquette

So over the last couple years, I've bought and sold 3 or 4 gloves on ebay. I've been dormant for a while, and a couple weeks back picked up a "New" Pro-30HFW to use for Softball. (The wife doesn't know about that one). The transaction goes smoothly via best offer, and after about a week the glove showed up stuffed in a 12x8x3 box. The glove was creased down the middle of the pocket because the seller had to fold it over to squeeze it in the box.
The seller knows the value of the gloves and audience looking to buy them. What really splinters my stick is that they charge $15 for shipping, then stuff a high end glove in a "Flat rate" sized box. The cost of the shipping doesn't bother me too much, but creasing the pocket of a glove to make $5 off shipping is HORRIBLE!
