Live or work in Manhattan? You now have an all-too-tempting way to impulse shop online. Amazon has confirmed to Mashable that its Prime Now delivery service is now available across the whole of the New York City borough, rather than the tiny area of before. If you just have to get some soap right after a sweaty Central Park run and don't want to visit a store, you can. It'll still cost $8 for the one-hour option (it's free for two) on top of your Prime subscription, of course. The big question is whether or not Amazon can expand Prime Now beyond Manhattan in a timely fashion -- that super-fast shipping depends on having a distribution center close by, which isn't as likely in less densely populated areas.
