So what do you do if you need a strip of LEDs for a project that you're putting together by this weekend and you don't have the right hours open in your schedule? (Or [insert random product here]?)
Just have it show up at the supermarket/drug store/gas station in a couple of days. Easy.
It's also cool that the apartment buildings can install the lockers and use them for packages which Amazon never touches, for the whole 'business hours' problem. But as Amazon's programs for offering free shipping to 3rd-party sellers are making it more of an 'Everything Store' by the day...well, it'll definitely be interesting to see what happens.
