There should be a minimum amount you can order of something online. Having a full on truck drive to your house to deliver a pack of AA batteries because you can't be arsed going to the shops is ridiculous.
@anon_opin that truck is rolling anyway though, while presumably you plan to drive an entire car containing nobody but yourself to the shops.
@anon_opin But if you're going to drive to the shops to only buy said batteries, it would be more environmentally friendly for a van making multiple stops to drop them off whilst they're delivering another package to someone else on the same street.
@anon_opin You miss the point - as others have said already. Your packet of AA batteries is offset by next door's dumbbells.
