I don't buy a lot of stuff from Amazon. Maybe half a dozen things per year and don't pay any shipping with this sort of "hack".
This works in the UK so I am not sure about elsewhere.
I know you are trying to stop Amazon but just in case there is the very occasional item that you have trouble getting elsewhere and you don't want to stump up extra for shipping.
If you can get the item delivered to Post Office then at the point you chose delivery there is usually an economy (free) option.
