Where are all the items in the pawn shop? There used to be tons of pages now there's only 1?

why does there need to be pages and pages of stuff in the Pawn Shop?

My bet is that some folks are going for the empty Achievement.

I am in there a lot. and there are always pages and pages of items

I don't visit it all that often. But there is an Achievement for visiting it when it's empty.

The CW section of it does get cleared out. I have not seen the sP section of it get cleared out since the Achievement was created, but this is also possible as it has happened in the past.

In RL one of the fun things about shopping in Pawn Shops is that the merchandise quantity and quality changes unpredictably.
