Walmart offers the Toy State Style 1 Road Rippers Street Beatz Vehicle in Green for $7.43. (Amazon charges about the same for Prime members.) Choose Site-to-Store pickup to dodge the $4.97 shipping fee. That's the lowest price we could find by $16. It features flashing lights, pulsing speakers that play music, and motorized forward drive.

Update: It's sold out at Walmart, however Amazon has dropped its price to $6.71.
