Any suggestions on places to buy a bulk quantity of quality sleeves for cheap (not ebay)?

If you don't mind the... "meh" quality you can get 100x penny sleeves for a dollar a pack at cool stuff inc. but aside from that, you're looking about $5 per hundred sleeves for quality

Potomac Distribution has some:
