I have recently been selling a number of similar items (collectible soft toys) and printing out 'in post locker' postage labels for them, and sending them this way. I have not really paid much attention to the buyers addresses. It has only now come to my attention because of receiving a couple of emails from eBay, that a couple of these have gone via the global Shipping Program. I had no idea I had this switched on, on the listings as I don't usually sell internationally. The emails state that the parcels have arrived at the global shipping hub. Am I liable for any more postage costs ? I am worried about this so any advice will be appreciated.
