Craig & Carmine explain ways they've learned to act right and not act right while buying/selling/trading sports cards on Facebook and Instagram. 

They talk about great interactions they recently had with international card collectors to get big PC cards, how to rest easy about a deal, and times they've been scammed or almost scammed in the past.  

Finally, they predict which cards will get the biggest price bump from round 1 of the NFL playoffs.
