Today only, Mattel cuts 25% off sitewide during its Cyber Monday Sale. (Discount appears in-cart.) Even better, it stacks onto items in its sale section, which are already discounted up to 75% off. That ties an October mention and is among the best deals we've seen from this merchant. Shipping starts at $7.49, but orders over $25 or more receive free shipping. Sales tax is added where applicable.

A best bet is the Hot Wheels 3-Lane Super Speedway for $65.99 before the above discount, $49.49 after. With free shipping, that's the lowest total price we could find by $33. It features lane changers that facilitate crashes, speed boosters to make the crashes better, and includes 10 Hot Wheels vehicles to give you something to crash together. It all sounds very violent, in an awesome way. Kids'll love it.
