hi can anyone help please, ive sold 2 items on ebay and when i try to generate the prepaid postage label i get the message, post from postcode is not valid. ive checked my postcode and it is correct, this has happened before and i ended up paying for the postage out of my own pocket even though the buyer had already paid for delivery when they bought the item, this is getting frustrating for me and ive tried to ask ebay but they just didnt get what i was trying to say. has this happened to anyone else and how did you resolve it please ,many thanks.
