COMC is great for buying low-end stuff in bulk, in my opinion. I'll go there and look for lower end PC stuff, and if I can find a handful of what I need, I'll make a purchase. Bought like 40+ cards there twice in the last month.
"I see great things in baseball. It's our game--the American game. It will take our people out-of-doors, fill them with oxygen, give them a larger physical stoicism. Tend to relieve us from being a nervous, dyspeptic set. Repair these losses, and be a blessing to us." -Walt Whitman
