Unlike most other retailers that sell video games, Amazon doesn't offer a regular weekly sale. Instead, it uses a more mysterious process for choosing which games to discount and when. So at any given time, you can usually find unadvertised sale prices on a selection of games, even if it's unclear when they'll go back to regular price. In any case, we've gone through the PS4, Xbox One, Nintendo Switch, and PC game discounts that are live now and highlighted some of the best ones below.

For starters, if you're an Amazon Prime member and you pre-order Call of Duty: Black Pro 4 before it launches on October 12, you'll get a $10 reward certificate. Even without a traditional campaign, this year's installment is shaping up to be an interesting one, thanks in part to the new battle royale-like Blackout mode.
