Lots of reports have been coming in the past few days of readers finding Walmart's Exclusive Black Series 6-Inch Stormtrooper (Mimban) at their locals stores. So far we have received reports from Michigan, New York, Virginia, Louisiana, Ohio and Pennsylvania.
Walmart's SKU # for this item is 667662952. Unfortunately you can't use a "inventory checking website" to check stock at your local stores currently because Walmart's inventory system mixes the SKU in with the Basic Black Series 6-Inch assortment and will references those qualities on hand as well.
These have yet to show up in my area of Texas. If you find this figure in other states besides the ones mentioned above feel free to post where you found it in the comments.
