Just got back from Staples. I had to buy more printer ink I snagged a ream of Hammermill Copy Paper for $5 with a $4 MIL rebate. I actually did the rebate online and it took about 30 seconds. A check for $4 should be coming within 4-6 weeks. $1 for 500 sheets of paper isn't bad.
I also snagged an Avery Heavy Duty binder since they are giving 100% back in Staples Rewards this week. Go. Get cheap paper!
