I opted out of GSP. For small items, the shipping cost to Kentucky AND the international shipping cost was too much for buyers. Another problem I encountered with GSP was that some buyers were not able to complete the transaction. Opting out allowed for international shipping preference to be set whereas with GSP, there were no choices. Not sure how much this was costing me in lost sales but we shall see what happens. Another wish I have is for GSP to be an option for high dollar items where the added protection is a benefit.
