I don't necessarily agree with the bits about 2-day shipping. TBH, I've had positive and negative experiences with that for years and don't really see a trend one way or the other. When it works well, it can be amazing (next day on a weekend!) and when it fails can seem really weird.

But I'll still mostly agree with your list and add another. A lot of clothing items now only have a reasonable return policy when bought as part of a Prime Wardrobe. What if I just want a pair of shoes and am worried about them not fitting? Some offer free returns for this and others don't. Ugh.
