We are traveling to WDW July 21st. I have a DS6 who I think might be interested in pin trading. Is it too late to buy a lot off ebay or website(need to arrive by next Fri)? And if not too late can y'all recommend a seller? What is a good number of pins to purchase? We will be there 7 nts and I bet he might want to buy a couple of pins that might be special to him( he loves Star Wars and Pirates). Thanks in advance for any help.
