Office Depot takes $20 off in-store purchases of $100 or more via this printable coupon. That's the best coupon we've seen from Office Depot since March, when a smaller minimum purchased was required. (This coupon also applies to select technology items; the March coupon excluded all technology.) Computers, monitors, projectors, TVs, MP3 players, video games, and video game consoles are excluded. Sales tax is added where applicable. Coupon ends June 25.
