Watch the Staples ads - they often have rebates on paper. I haven't paid for copy paper in a year - I just go when they have the rebate and buy 2 reams. Usually $8-9 out-of-pocket, but tgen the rebate comes in a few weeks. They sometimes have it on the cases of paper, too. Sam's Club and Costco are the best deals, otherwise. I used to buy a case at Sam's before I started getting it at Staples.
