Dear Ebay:

GSP should be a customers choice. If the buyer doesn't want to comply with Pitney and Bowel rules, then other shipping options should be available upon request. Buyers should have freedom of choice, and Ebay is depriving buyers from that.
The GSP is a good system as long as shipping could be combined, or smaller items that fits in a normal enveloppe and with low value can be shipped for low prices. Sometimes you do not need a $23,- courier to ship a $6,-, 80 gramm item that can be shipped through USPS for as little as $3,39.
Greetings, Pim Sonnenberg
