Where to buy a pin trading book / binder?
PAX is almost a month away and I'm trying to get ready to trade pins! I'm pretty new to pin trading and last year I saw people with books and binders to keep there pins in, while I had a box. Everyone was too busy flipping through each others books and binders to dig through my box. Where can I buy one of these pin books without spending too much money? I don't really know what they are called so I was having a hard time finding them online.
