Trails series

As someone whose close to finishing the Sky Remake,

I’m amping up to start getting the other series in order. But I’m a physical copy kind of guy vs digital.

As I’m briefly browsing through GameStop, some of their ps5 copies for trails are like “coming soon”. Like CS 3/4 bundle or even the Reverie title

As a new fan, is it pretty normal to have such a low quantity of copies in places like game stop?
