What's the con­cept be­hind Ama­zon that tells you to make some mon­ey by sell­ing "past pur­chas­es", that in their own data­base still have a fu­ture es­ti­mat­ed de­liv­ery date? And they have a re­turn pol­i­cy so I can get all my mon­ey back, like if the ship­ment ar­rives as a box filled with shat­tered stuff. Why don't they just ad­ver­tise with "don't buy this crap and save 100% (+ ship­ping)"?
