Amazon's automatic Dash refills are reaching all kinds of devices... and now, that includes the gadgets in your fridge.

It's not cheap at $45, and that's not including the $6 you'll pay every time you need a new filter. However, it might be just the ticket if you can't imagine drinking from the tap (or heading to the store) for even a brief moment.
