There's a mistake on one of the articles.

https://www.gamespot.com/amp-articles/huge-ps4-sale-begins-on-psn-just-as-the-last-one-e/1100-6469261/

This article says that BO4 is on Sale but the link provided is for BO3. The correct game on Sale appears to be BO3 with the Zombies.

There's no comment section in the article so I don't know where to post.

@xlsavagelx: Hi there, this isn't really the place to post this, as this forum is for moderation related questions. But I have looked it over to confirm the mistake and passed it to staff to have a look into as well.

@zanelli: Thanks I checked the Article and they have changed it!
