Amazon offers Prime members the Revell Star Wars Snaptite Build & Play Imperial AT-ACT Cargo Walker for $12.01 with free shipping. That's the lowest price we could find by $2, although we saw it for $5 less two weeks ago. (Some stores charge $20 or more.) It features battle action sounds and a motion-positionable head, feet, and legs.

A close price, Fry's offers it for $12.99 with in-store pickup.
