A higher-yield, $104 black lasts for 4000 pages, or 2.6 cents per page. The 2600-page cyan, magenta, and yellow cartridges cost $120 apiece, for a per-page, per-color cost of 4.6 cents per page. At its cheapest, a four-color page will cost you a middling 16.4 cents.
In honor of its first anniversary, Blizzard released a digital Game of the Year edition of Overwatch on May 23, 2017; it includes all content from the Origins Edition in addition to ten free in-game loot boxes.
The Anniversary event will end on on June 12. Overwatch usually updates at 2 p.m. Eastern time. However, with the start of this event on May 23, the company changed that to 11 a.m. Eastern. So the same thing might happen when it ends. Don't count on those extra few hours to get the Anniversary skin or emote you've been hoping for.
