Free Blitz in store question

[d.s.gardner.2013]

Didn't know where to put this post....
In the store under items is an item called "Free Blitz".
It cost 395 balens. But it doesn't say how many days it is active.
Does this mean, it's permanent?

31 days, same as all the other parts of Spirit cov are individually.

Thanks! Wish they said it on the item like all the others.
