Hi Dumdum,
Welcome aboard!
Another interesting issue with this GSP is that once ‘selected’ by seller, once the auction is closed & won by someone, there is no way to then agree between seller & buyer on an alternative shipping (typically cheaper, at buyer/my pre-shipping agreed full risks) mean. About ~ one year ago, when this new stuff was introduced, I won an auction w/i having noticed the GSP shipping was On & very expensive. Once auction was won, the seller accepted to try to reduce the shipping price by re-putting the same auction for sale on Ebay, with different shipping method, on Buy it now mode this time @ the price I had won the auction. Guess what happened? Someone else was faster than myself to bid & win the auction? I was grey...
Cheers,
JD
