This is putting me off using Amazon. I was opted in to a free Amazon Prime trial during a recent purchase a month or so ago, which I decided to go ahead and use (Amazon Prime is free and quickish shipping). After my order arrived, I cancelled Amazon Prime (I got an email confirming) and I took my debit card details off Amazon. I bought a few things on Amazon last week and at no point was Amazon Prime mentioned during any of the transactions (I paid delivery on the items). My card annoyingly was stored on Amazon again, and a few days later, Amazon sneakily went ahead and charged me for a year's worth of Amazon Prime, which is $80. Luckily, I was able to get a full refund because I hadn't used Amazon Prime for anything since getting charged for it (and it was actually just a 3 click process, so no complaints on cancelling it). I'm just furious I was signed up for this service (cancelling the trial clearly did nothing, despite a confirmation email), especially when they debited my account without notice or me confirming I even wanted it. Just beware in case you end up caught up in this and unknowingly use Amazon Prime.
