The Iron Man 3 Hall of Armor Set, which quickly comes in and out of stock at Amazon.com (though it’s in stock as of this writing), has made its way to a few other online retailers. Now both Walmart.com and Target.com (click the links to go to the product pages) have the sets listed. Not only that, they appear to be in stock right now! Walmart has the set listed at $34.96 while Target has it at $39.99.
Get them while you can. Good luck!
