Target offers the Robotime 3D Wooden Robotic Puzzle in Motorcycle Sidecar, Off-Road Utility Jeep, or Missile Transport for $19.98. Add two to cart for $39.96 and to bag free shipping. That's $2 under the lowest total price we could find for just one of these puzzle toys elsewhere. Once assembled, these vehicles can be driven via remote control. Five AAA batteries are required (not included).
Of note, you can also buy one for $19.98 and pad your order over $25 to get free shipping; otherwise, shipping costs $6.19.
