"Amazon doesn't disclose Prime membership numbers"

"The numbers were based on surveys of 500 U.S. residents who made a purchase at Amazon.com in the period from October-December 2015"

Lot of bold claims here. Just a few ways off the top of my head for why this estimate is ridiculous:

- People who use the Internet are more likely to be Prime members. We have elderly people here.

- People who've made a purchase on Amazon are more likely to report being prime members.

- People who made a purchase during the holidays are far more likely to be Prime members (I was a Prime member this holiday season, because I finally cashed in my free month and cancelled).

- 500 people is far too low a number to extrapolate such a bold claim about Americans.

- I'd even argue that people who fill out surveys may be more likely to be Prime members.

In short, Consumer Intelligence Research Partners sounds like a joke.
