Does Tractor supply Company sell products on line to customers?

I just looked at their website. They have a few products available for online sale...but really, their product line is either so heavy or bulky the shipping cost would exceed the product cost, there are too many hazmat regulations involved in the shipment of it, or its sale is controlled...like they sell penicillin to farmers. It can't be mailed to an end-user. So this is a company that doesn't need to embrace the online revolution.
