> a yearly subscription that makes delivery of most products free Which is great marketing trick, because you are of course paying for delivery through inflated unit prices. A lot of things on Amazon are a few Euros more expensive than in other stores because they just hide the delivery fee in the unit price. There is no such thing as "free delivery", you are paying for it one way or another.
The prices on Amazon might be "a few euros more", but where I live, the delivery fee for getting e.g. a 65" TV delivered from Best Buy or Costco, would be more like an extra $30-$50. (And I don't own a car, so I can't just go pick it up from the store, either.)
What I'm trying to say is that often stores that don't offer free shipping are cheaper than Amazon and you should compare the total prices instead of just ordering from Amazon assuming that they are the cheapest. In my experience they sometimes are the cheapest, but in most cases they are not.
