Walmart offers the Marvel Avengers Boys' Dress-Up Costume 2-Pack
Captain America and Hulk
or Iron Man and Hulk
(pictured) for $5
plus 97 cents
for shipping. (Free Site-to-Store pickup is also available.) That's $4 under our December mention and $28 below the lowest total shipped price we could find for two of these costumes elsewhere. Sales tax is added where applicable. They fit sizes 4 to 6X, and each includes a mask.
Also available is the Boys' 3-Piece PJ Set in Batman or Superman for $9.50 plus 97 cents for shipping. That's $5 under the lowest total price we could find for such a set in either style, although we saw a similar set for pennies less last month. Each set includes a tee, pants, and cape. It's available in sizes 12M to 24M and 3T to 5T.
