Walmart offers the Huffy 12-volt Electric Green Machine Scooter for $49 with free shipping. That's $30 off list and tied with our June mention as the lowest price we could find. (It's around $8 cheaper than what some third-party sellers charge via eBay.) It travels up to 8mph and features a steel frame and rear foot brake.
