Just got a sales email from Harbor Freight this morning. It includes a coupon for the basic tire changer equipment for only $37.99. That doesn't include the motorcycle tire change adapter, but if you need the basic machine to get started, this is a 36% savings off the regular price of $59.99.
If you want to take advantage of this sale and want the coupon, PM me your email address and I will send you a copy... The sale runs through Monday, September 29th.
