Everyone saying it's your fault for not knowing about fraud detection and using multiple cards: I disagree. The issue here is simply that amazon has no cart for ebooks. Period. And that they did not reach out about the transactions before taking action (or even after blocking, who knows… they could have reversed the block).
Using Spendesk means generating a new card for each transaction. Having a single transaction to load "credit", and then use up that credit means more accounting work and simply adds friction, which is the original point of the post.
