Who wants to leave the house to buy a 1.5-ton belt sander? Thankfully, that and millions of other items are only a click away on Amazon.

It's not surprising that you can buy some wild items on Amazon, but it is a little shocking that many heavy items — including the belt sander — ship for free. 

It's impossible to calculate exactly how much Amazon has to dish out to ship these heavy objects — that depends on where you live, and which warehouse has the item. But cutting down on shipping costs, especially on orders like these, is probably fueling the company's entry into the freight business.

The heaviest object we could find that ships free on Amazon is this three ton powered lathe. Weighing significantly more than a car, and requiring special delivery agreements — no one-click ordering available — you'll have to be home when it's delivered. But with something this large you'll probably want to be around when it arrives.
