Maybe you have a giant 5K count box of cards shelved under your bed that you’re looking to unload. Or maybe you just want to exchange your foil Archangel Avacyn that you just opened in the prerelease for some cash. Nowadays, there are more options than just eBay and trading at your local game store, and it can be a little overwhelming — maybe you don’t have time to play in FNM and trade with the locals, or maybe you’re just plain bad at trading (I know that feel).
Travis Allen from MTGPrice has written a fantastic blog post on the pros and cons of different ways to sell your cards, from eBay to TCGPlayer. And he even includes the best ways of packaging and shipping them to ensure they don’t get damaged in the mail.
