A handful of people having a whinge to ebay about the GSP is not going to stop them using the company. They are making bucket loads of money from them. The US/UK sellers love it because they are protected against unsavoury buyers.

I avoid the GSP, so have nothing to whinge to ebay about. Unless it's for a large item, where often the GSP is 1/4 of the price of USPS. Then, I'll even ask a seller to change the listing to GSP for that item.
