Walmart offers the LEGO City Great Vehicles Monster Truck for $15.99. (Amazon has it for the same with free Prime shipping; Target charges the same with free in-store pickup.) Opt for in-store pickup to dodge the $5.99 shipping fee. That's tied with last month's mention and the lowest price we could find by $7. It features a buildable ramp, working suspension, and comes with a driver minifigure.
