I dislike Amazon but yes, my experience in what you have outlined is that it's generally amazing.

The parts that aren't amazing is getting items that aren't representative of what I ordered. But refunding is always a breeze when that occurs.

My problem is that it shouldn't be a thing that happens so often (to me). I shouldn't be shipped shoes of the wrong size 3 times before I get shoes of the size I ordered. I shouldn't be buying open box items without being told it's open box. I shouldn't be buying things with the completely wrong thing in them.

Now, all of these can be problems with big box retailers. But the sheer frequency it happens to me on Amazon - it's never happened at this frequency to anyone I know when we would shop in store. Yes, my friend once bought a graphics card at Fry's that just contained a box of rocks. But that was one friend, one time. I've had more of these issues on Amazon, the last ~7 years, than I have for all shopping experiences everywhere else that I've ever shopped combined.
