How do they get transaction history even for transactions involving non-Amazon-owned companies?

    I'm not sure about that but Amazon has my AMEX purchase history. I've been retargeted for single item purchases that are impossible to know otherwise.

  The stores and credit card processors sell the information to Amazon, Google, etc... There was an article in Forbes or Bloomberg or something recently that stated that Google now gets something like 80% of all credit card transaction data, online or offline.
