Star wars sold out pins
That's too bad they don't release a limited number of pins for sale each week to make sure they can sell something every weekend of the promotion. Knowing they are sold out might prevent people from going since there's nothing for them to buy. I don't know if this is a real solution or not but companies at San Diego Comic-Con have started to do this during the convention in order to assure each day they have items for people to buy in case they couldn't come to the begining of the con. One year, everyone sold out of their exclusives on the first two days and the convention was empty the last two days.
