It's not a generic UPC. It is dedicated to the STAP only.
Well, after exhaustive research and several hours on the phones with TRU locations across VA, I can pretty much confirm that this is not the case.

When they look that # up in the computer, it shows counts for the whole deluxe vehicle/fig line, not the STAP specifically.
I had several stores say "yes, we have that" only to show up and there are none on the shelf. I've had several others scour the aisles and backroom for the specific item but they are never able to find it, despite showing multiples under that code.
It's really the Item # I am going to need, not the UPC. And since it is STILL not on their website, I guess I am SOL on ever finding this stupid POS.
If anyone stumbles acros this in NC, WVA, DC or Maryland please let me know and I will make the road trip. Thanks!
