The Offer
- Receive an instant discount of $15 when you purchase $300 or more in Mastercard gift cards from OfficeMax or Office Depot

The Fine Print
- Limit of two discounts per household/business
- Discount applied at register
- Cards issued by U.S. Bank
- Valid from September 4th until September 10th, 2016
Our Verdict
This will stack nicely with the American Express offer for $20 offer $100+. If you don’t have any offer on any cards, make sure to use a card that earns at a high rate on office supply stores. They just recently had the same sale but on Visa gift cards.
