Reminder: all the direct person-to-person sales are to be done in the Classifieds section, accompanied with appropriate details such as listed prices, photographs of the goods, etc.
Also if you got an extra you didn't pay for, it far more considerate to check with the GB organizer before immediately trying to make even more money on something you did not pay for. It could mean that someone else will now be an item short.
