Easy tiger. Maybe it's a problem of vocabulary (non-native english speaker here) with "People favor doing things at the very last possible moment." ?

What I meant was that of all days, people buy on the very last. Which makes sense according to our intuition indeed. I didn't mean to imply that (number of people buying the last 5 days) > (number of people buying before during the whole year) as you seem to argue against. I was only observing that absolute numbers increase day by day starting 5 days before Christmas.

Your early buyer-late buyer model is interesting but as you said, it would require more thorough research to set it up and was not in the scope of the article.

I thought the data was interesting and wanted to share it with the community, and I had no ambition to draw a complete buying model from it.
