Confusion with return label

[toysandmoreuk]

Can someone confirm to me how the ebay return labels work? I just did a return on an item over 2.1kg and noticed that ebay only charged me £3 something. Now I'm starting to believe they have sent a return label for parcels up to 2kg. Am I now going to have to spend money on another label or will I get charged extra when it arrives at my door? I'm sorry but it seems that all these changes ebay have made have made everything so much more confusing. There seems to be no simple explanation to anything on the site nowadays

On eBay.com the seller doesn’t get charged unless the label is used and it’s  a USPS return service label so it covers up to the maximum weight allowed by USPS (which is pretty high, not just a few pounds). I’m not sure if anyone here knows how a UK return label works, you might to want to ask this on the UK boards.
