well recently i sold a few gba games and they are so light and thin, so i just popped them into a normal envelope, attached a first class stamp and put them into the post box. I thought this would be fine. I have received positive from most of the people that purchased them, however 2 people(out of about 16) messaged me saying they had to pay 1.09 (1.00 handling and the 9p me guessing to upgrade 1st class stamp to a 2nd class large letter stamp) Could they just be lying to get some money back? or is this true? as i received positive from other people. 1 of them even sent me a message saying the game got sent back to me, i paid the postage then it got sent back to them. But it didnt get sent back and i didnt pay postage because the buyer pays postage at post office to retrieve the game usually dont they?
