According to @JohnSerwach on Twitter, Officemax is offering $10 off the purchase of 2 $50 Visa gift cards in-store. $50 Visa Gift cards cost $4.95 each, thus making the cards free.
Visa gift cards sold by Officemax are issued by Metabank and can be loaded to Bluebird/Serve at Walmart by using the last four digits of the card number as the pin. (Recent reports suggest you don’t even need to enter the pin for such low dollar amounts.) They can also be liquidated at Target by loading to a REDbird.
At this time it is unknown whether this promotion will work on higher denomination gift cards, however the sign specifically mentioned $50 gift cards only.
John also didn’t pass along the expiration date. Note: Despite being part of the same company, in-store Officemax deals are generally not available at Office Depot.
Update: This deal appears to be good at both Officemax and Office Depot through 3/7/15 with a limit of two per person/household. Officemax sells cards issued by Metabank which can be loaded at Walmart. Office Depot sells Vanilla branded cards which have been known to have issues when loading at Walmart.
Update 2: You can find a detailed analysis of this deal along with information about a possible glitch that allows for more savings over at Miles to Memories.
The best way to maximize this deal is to purchase the gift cards with a Chase Ink card to earn 5X Ultimate Rewards points on the purchase. You can also earn 5% cashback with the American Express SimplyCash Business card.
