If you have a Staples Reward Card, and also recycle your used ink cartridges, then you should receive Staples rewards certificates. Between home and Troy's office, we go through quite a few ink cartridges, so we accumulate nice rewards every so often. This week, I bought 2 packs of Zebra brand ink pens, and 1 pack of Bic mechanical pencils. I also bought a pencil box. Everything was on sale, or had an Easy Rebate offer with it. Total cost of this purchase cost me $1.07 out of pocket at the register, but then I will receive a $2.49 rebate check in the mail for the Bic pencils. PLUS, I still have $15.00 in rewards certificates to use. . .
