It isn't that bad, I started to buy locally and it's true that sometimes it is a bit more expensive but just for a few euros, and sometimes it is the same price.
I also found that if you look for the original vendor site you'll find it probably cheaper than amazon.
And on the other hand cancelling prime will save me 50€ a year.
Let's not sell our souls and destroy our local economies for saving a few bucks that won't go anywhere anyway.
