Through 9/5, Staples has a 5000-Sheet Box of Hammermill Copy Plus Copy Paper on sale for only $21.99 after this $13 easy rebate. That's over 50% off its standard price point and one of the best paper deals currently available on the web. The landing page is a little confusing: they're describing an entirely different product in the description section, however the deal is functioning properly after adding it to your cart. There is a limit of two rebates per household. Shipping is free with $50 and sales tax is charged in most states.
