Amazon shutting down shipping?

The way my nefew explained it, they buy/ own most of their products. That is when you order, they buy and sell to you. He wasn’t there long. I know nothing about them. Curious myself. Don’t think there’s much dryvan freight paying much over 1.50 pm right now. Lucky to average that, from what I’ve seen. But, then again I’m always the lowest paid of any Truckdriver I’ve ever met. For some reason they go out of Bussiness or turn in their Trucks. Can’t understand why, they’re always making such a killing. Just can’t figure it out.
