A best bet is the
Matchbox Cliff Hangers Police Station (pictured), model no. X0360, for $6 with free shipping for Shop Your Way Max Members; otherwise shipping adds $6.50. (In-store pickup isn't available.) That's tied with our March mention and the lowest total price we could find by $6. This playset clamps onto a table, door, or other surface and features multiple levels, working elevators and clamps, and one vehicle.
