Amazon actually doesnt make much money on it's store. It's their tech business that makes it all. You can hurt them more by using them, but _only_ for the great deal loss leader products that they use to attract customers. Take their free prime trials(say youre a stupid to get more) then send shit back saying its broke if you dont like it. Order little things in single orders so it costs more to ship than the small margins they make. If a package isnt delivered to you door? It most likely was stolen, get your money back. I definitley cost amazon more money than they get from me
