Yep. They also used to drive unmarked vans for a while, but now I see blue Amazon Prime delivery vans everywhere. I still get an occasional item from Amazon delivered by someone else(I guess they still use other couriers when their own capacity is out) but 90% of the time it's delivery by Amazon. And it's much better than anyone else, they give you a relatively precise 2 hour slot and you can see where your driver is on the map. Only DPD did that previously, and even then not for every parcel.
