We all know the delivery struggle. All the world's couriers must have trained at Ninja School or something, because more often than not, you'll receive a notice of a delivery "attempt" at your apartment rather than the package itself.
Plus, if you've ever lived in an apartment complex filled with a bunch of thieves, you know how frustrating it can be when you've received an email that your package was successfully delivered, only to later discover that the building's resident crackhead stole your baby clothes for ramen noodles and needles.
So Amazon, hoping to make the delivery process more reliable, decided it'd be a good idea to develop a solution that would ensure people had their packages delivered right to their homes. It's called Amazon Key.
