Feels like if this takes off there'll be an opportunity for arbitrage between TCGPlayer and Mana Pool. I see e.g. All Will Be One is $11.67 on TCGPlayer and $12.40 on Mana Pool. Though I haven't done the math to see what kind of fees there are.
Part of my interest in this project came because i was writing software to arbitrage TCGplayer and eBay around last Christmas, because I was wasting time doing it manually and wanted to see if I could automate.
