Yes, exactly. I believe people are misunderstanding my comment. No matter what processor you use, depending on how Amazon decides to refund you it will absolutely become a hassle for the customer. It's just inherent - it's not really a "problem" tho, not anymore so than trading stocks. If you bought Bitcoin for a buck a decade ago and bought a GPU for Christmas and decided on New Year's Day you'd like to return it, but Bitcoin changed price you'd have to deal with a lot of tax stuff. There's no payment processor that can resolve this.
