Looks like Electronic Arts isn’t the only one making pricing mistakes today. Sony Computer Entertainment put Grand Theft Auto V on the North American PS4 PSN store marking it as “free” as you can see in the picture at the bottom of this post.
Before you scramble to take advantage of the mistake, unfortunately clicking on it only returns a “The content cannot be selected at this time” result. Looking for the game on the web store returns the correct $59.99 price.
Someone at Sony probably messed up a checkbox that caused the PSN store to use the demo template, as indicated by the “Check it Out!” message instead of “Pre-Order Now”
The mistake is most probably bound to be addressed soon enough.
