I don't have amazon on my phone due to the bloat and opt to wait until I get in front of a desktop. Which means probably 80% of potential impulse buys from my phone are forgotten by the time i'm back home and they've missed out on sales. It's lost opportunity that they can't measure and so it will forever be swept under a rug.

You might be the exception here but (a) Amazon.com is accessible from your mobile phone, do you not use that? And (b) “impulse buys from my phone” is indeed hard to quantify. How do we know that you’d make any impulse buys if the app was in front of you? Going to their website on a phone is as easy if not easier than using their app and the content is identical. Yet you don’t say that you make impulse buys that way. 80% of 0 is still 0.
