Just walked out of here, not only did they not carry the tri-color ink for my HP printers (940XL) but it took almost 10 minutes for someone to help me. At the register I had 2 coupons (one fore $10 off $40, and one for $5 off $25) but the cashier refused to honor both; though I had enough items to split into 2 transactions in order for both coupons to be valid, he refused to do it. I cannot say I will purchase ink, toner or anything for that matter from Office Max again. If you enjoy saving money this is not the place to go.
