Just got back from returning a package to Amazon for SD22.

It occurred to me that returns are free to us, but cost Amazon (though I'm sure they have a deal with the post office).

Wondering about the viability of ordering large items from Amazon (with free shipping), then sending it back on a free return.

Yes, it ties up your money for a couple weeks but, in the end it costs you nothing but it costs them to ship and return ship.
