I’d advise anyone buying e-books on Amazon to think it through carefully. My account was banned recently because, years ago, I ordered two paper books that Amazon said would be split into two shipments. Both books arrived without any issues, but later Amazon refunded me for one of them, claiming that one package never arrived. This happened 4–5 years ago. Apparently, during a recent review, they decided this counted…
Fast forward a few months, I never received a refund and they claim they have no record any more. I could chargeback my credit card but I imagine I'd also be permanently banned from Amazon - so instead I accept they've just stolen $1000 from me with no recourse...
(if anyone from Amazon is reading this, my email is in my bio!)
