Walmart continues to offer the Coleman Off-Road 100cc Go-Kart in Red for $599. Choose in-store pickup to dodge the $69.97 shipping charge. That's tied with last month's mention and the lowest price we could find now by $70. It features a 4-stroke, 3-horsepower motor, 16- and 13-gauge tubular frame and roll cage, 4-point safety harness, and 150-lb. weight limit.
