Groupon offers the Hot Wheels A.I. Racing Starter Kit for $69.99 with free shipping. That's the lowest total price we could find by $6, outside of the below offer. This racing set features artificial intelligence that keeps the cars on the track; it includes two cars, two controllers, and 20 pieces of track that can be set up in over 40 configurations. Deal ends December 3.

Thinking of buying more than one as gifts? Target offers it for $75.99, but you can add two to your cart for a total price of $113.98 with free shipping. That works out to $56.99 per set, which is $17 under Groupon's per-unit price. This deal ends November 26.
