Amazon has "Amazon Invoice Verification" for sellers selling large quantities of merchandise. But I personally do not want Amazon trying to check if Mr. Doe just wants to sell a couple extra tubes of deodorant he bought by mistake. Can that be abused by thieves? Sure, but not everything is fixable.
