Hasbro's line is that it is Walmart's exclusive and they do what they want with it.
The long and short of it is that Walmart does not make an effort to make exclusives available at all stores. Some stores will carry certain exclusives, others will not. The website says it best -
It's sort of a crap shoot. If you go to Walmart.com
and search your zip code, it will give you a list of the stores near you that were scheduled to get Jabba -
"We found X stores within 50 miles of [zip code]. Only stores that carry this product are shown below. (In-stock status is approximate and was last updated on DATE at TIME, E.T.) "
The only bad part is there is no way to tell what's happening at those stores. Only thing you can do is contact one of those "carry this product" stores and hope to god that you find the one employee who knows what they are doing (long odds, I know).
