anecdote: I use Amazon for practically all of my shopping, only supplementing it by going to a brick-and-mortar for food.

I have never used the "buy now" feature, so honestly I think it's impact is a bit overblown.

Here are my reasons I never use it:

1) I do a lot of comparison shopping, so I like to review my orders before the final purchase. (in case I put something in my cart and then later added something better)

2) I want to make sure I don't order something under $35 and get stuck paying for expedited shipping (which is free for prime members over $35 in purchases)

3) I have a few addresses and cards on file, and want to make sure the order will use the right one.

4) I use the cart as a temporary list, anything that looks interesting during my shopping session gets thrown in there (or perhaps another browser window if doing comparisons).

Yes. I live an hour from big box stores so I know my UPS driver by name.

5) I use my cart as a queue of things to buy that I don't need "right now". I'll let things pile up in there until I do need something. I think it is a waste of fuel, boxes, etc. to place an order every day of the week instead of one box a week.
