According to the Target app, the game is in stock at a bunch of my local stores. Visiting in person, however, reveals none on the shelves, nor yet a spot for them (and thus no code for me to ask about in back). So looks like they are on site, waiting for the nebulous release date.
The wait continues.
Have you tried asking the employees? Some of them are going in the back to retrieve a copy! I know one of them near me did, that’s how I have a copy.
Need to know the number they use, so they can locate where in the back the boxes are. Unless they just happened to know where the box was before hand. Usually something ### ### ####
Think it would be the UPC number? Or something internal they use?
Internal. It’s ### (department) ### (subset) #### (specific item). Ah well, one day soon.
And we already have box inserts out there! 
I got this laser-cut wood insert, and it is working out really well: Horizons of Spirit Island Insert Wooden Organizer - Etsy.
This one looks pretty good, also, but I wanted wood over plastic. 
I especially like the fear deck holder!
