In this case, as opposed to an eBay deal, which we've seen several times already via the ebay Seller GiftCardMall, the giant office retailer Officemax is running the deal. The deal can be at the link above.
In this case, buyers can grab onto a maximum of three $50 gift cards, but pay only $40 for each. That amounts to a 20 percent savings for anything you can purchase at iTunes, meaning TV shows, movies, music, and apps.
There isn't a solid date listed on the site, but we expect this is a limited supply of the cards, so get them now while you can.
Normally, OfficeMax charges $2.49 for shipping using USPS Critical Mail. In this case, and in other deals we have seen, shipping is free. The "Critical Mail" reference actually makes us think that the order will be fulfilled via Gift Card Mall; to be clear, the eBay seller fulfilled an earlier deal for Staples, too.
In addition, there are no sales tax charges on the gift card, despite the fact that OfficeMax charges sales tax in most locations, due to its national coverage.
To be clear, these gift cards are valid only in the U.S. iTunes Store.
