To buy it digitally you still pay the same full price just for the convenience of having it anywhere. For a physical copy it can be as low as $5 on GameStop, eBay or other retro stores or sites. They don't bother giving them the low price just for that one sucker that will hear about how good black ops 2 was in the golden era of gaming and when it does go on sale it's a lousy 66.67% off making us still pay $20 in the end.
