One of the coolest things about the Trade Conference are the promos, specifically the ones from Donruss/Playoff (Panini). Their black boxes are always packed with a ton of exclusive stuff. Some years there might be cards inside and other times you might find printing plates. They can be pretty expensive, but thats because the Trade Conference is the only place they could be picked-up. I opened a box from 2008 and pulled a bunch of one-of-one’s. Trust me, these are a very fun product to rip.
