Microsoft is offering $10 gift codes with purchase of select Xbox One games through now January 3rd, and there are a couple of good deals to be had if you weren’t able to get what you want for Christmas or in pre-holiday sales. There are, as usual, a couple of caveats. It only is applicable to games that are $19.99 or more, and buyers are only eligible for up to five of the $10 codes. However, when browsing the list of 65+ titles, a few can be had for a net total of $9.99 when you factor in the free $10 to be used on a future purchase.
