We're not ruling out that Amazon has simply stockpiled its products in key locations to facilitate quick deliveries, but other companies didn't have the opportunity to do that—in category after category, Amazon's products ship in a few days while top competitors won't be out the door for a month. For example, All of Amazon's Fire TVs arrive in a couple of days, but most Roku boxes won't ship for weeks. Smart speakers like the Echo Dot and 3rd Gen Echo? On your doorstep day after tomorrow. Meanwhile, many of the other smart speakers on Amazon are delayed.
