Toys"R"Us offers the Play-Doh Marvel Heroes Assemble with Can-Heads for $4.98. Opt for in-store pickup to avoid the $5.99 shipping charge. That's the lowest price we could find by a buck. It features Iron Man, The Hulk, Thor, Black Widow, Captain America, and Hawkeye-themed cans of modeling compound, stampers, and an extruder.
