OfficeMax cuts 20% off most items sitewide via coupon code "JULY4". That's one the best sitewide discounts we've seen from OfficeMax in recent months, although we saw the same offer with fewer tech item restrictions a month ago. Shipping starts at $7.95, but orders over $50 qualify for free shipping. Many exclusions apply, including computers, monitors, tablets, TVs, and more. Deal ends July 6.
