EDIT:
So I got a reply from the seller and they're not sure if the parcel would be sent back to them because it was sent through the global shipping program. Can anyone tell me more about this?
I have heard nothing but horrible reports regarding the use of the global shipping program.
Same, and I'm so annoyed that eBay AUTOMATICALLY checks the GSP box when you sell an item, so you have to watch for it and uncheck it every time.
I've also heard of sellers sending well-packed items to the GSP center, only for the Global Shipping people to unpack their box and put the item in a different box with insufficient packing. (To cut down on the weight so they can pocket more money?) Just a word of warning to anyone selling fragile items.
Edit: I just figured out there is a way for sellers to opt out of the Global Shipping Program. Go to My eBay, Account, Site Preferences, and scroll down to the GSP line and Opt Out.
