Not only that but...
-We'd have to go out of our way to find stuff
-We'd have to waste our time at the post office AND pay shipping
-And hope that you'd even send something in return (hey, you never know)
-And even if you did send something, we'd have to hope it was of at least equal value
-And in the current state of the world, our stuff seems a more valuable commodity

So in essence, nobody wants do deal with this hassle. Just buy stuff online.
