Look your insurance certificate at the bottom it may say excluding courrier which means you'll need to upgrade your car insurance as if you are stop by the police your car insurance is void because your carry deliveries same if you crash. I upgraded mine to business use and it cost me an extra £20 a month so I'm covered no matter what. If amazon gaves the Insurance great if not that's fine I'm coved. Personally I would get your own to make sure your covered and to keep you right. That's my own opinion.
Only standard car insurance. At the moment they provide additional 'hire and reward' insurance needed, although the excess are very high if you ever needed to claim. They say they'll give 60 days notice if this changes.
I got the same question if you know about it let me know please?
