Amazon delivery options miss the most important information

Just look at this and tell me what's missing:

It has all the fancy options on how fast to get your order, how to group them, and even lets you sign up for free trial of Amazon Prime.

What's missing? Any indication of how the packages will be delivered - by mail or by courier. This matter quite a lot since packages sent by mail I can pick up from the post office any time I wish, while courier packages are a huge pain in the ass to get if courier misses me.

Meanwhile all the delivery time estimates are just estimates, and as often as not package will come earlier or later than the estimate anyway.

Seriously Amazon, you can do better than that!
