Staples retail locations offer the HammerMill Copy Plus 8.5" x 11" Copy Paper 500-Sheet Ream for $8.29. This printable coupon and Easy rebate drops the price to 1 cent. (The link is for reference only; you can't purchase it at this price online.) That's tied with our mention from two weeks ago as the lowest price we've seen and the best deal now by $10.
Also available at retail locations is the Staples 8.5" x 11" Multipurpose Paper 10-Ream Case for $19.99 before the printable coupon and Easy rebate, $9.99 after. (This also must be purchased in-store to receive this offer.) That's the lowest price we could find by $35, although we saw it for $10 less via mail-in rebate in January. Deals end August 27.
