Staples has a couple of great deals on paper available now; get a ream of paper for just a penny, or 10 reams for 10 bucks! Both of these involve the Staples Easy Rebates, which are super easy. Here are your deals:
Staples
Staples Multipurpose Paper $7.79
Use Easy Rebate form to save $3.98 off purchase (this will also trigger the online rebate submission info to print on your receipt)
= $3.81, submit $3.80 Easy Rebate
Final = $0.01! (limit 4)
I would do this one four times, and wait for another stock up deal. If you go through paper like water, however, you may want to do the following deal:
Staples Hammermill Paper, 10-Ream Case $53.99
Use Easy Rebate form to print online rebate info
