I always thought TRU Product ID was their SKU number. I've used the SKU before and it's worked - unless he changed the site at some point? TRU SKU for GI Joe is supposedly 477885, but that doesn't seem to work.
Usually you can find the EB Games SKU by looking up the item on their website:
https://www.ebgames.ca/Toys-Collectibles/Games/782960
SKU is 753289 there, but again, that doesn't seem to work on stocktrack (at the moment?)
So now I'm as confused as you are!
Another note: for many things at Walmart (figures in particular), individual item UPC's are all tied in to a single SKU. So searching for a specific figure by UPC (say, Destro) will show you stock for ALL of the Classified figures at the store - it could just be all Roadblocks, but you won't know until you go to the location. At least, that's been my experience with Legends and Black Series.
