Would you buy less books if you had to click a confirmation window?

It's much easier to buy books when you don't need to wait for delivery, unpack, carry around, get up to get them, etc. But your process already consist of several clicks and waiting for many pages.

People may self-report "no", but the evidence is abundant that at the margin, the answer is "yes". You are some probably-some-single-digit percentage less likely to buy. That matters very little to you as an individual, it can be life-or-death for a retailer.

Isn't it well-documented that the more steps you have during th purchase process, the lower your conversion rates? I'm sure this is especially true at Amazon's scale.

To be specific though, if I'm on my phone and I see a confirmation window, I might postpone the purchase until I'm in front of my computer - and by then I might forget about it. One click purchase completely bypasses these types of scenarios.
