Must have missed it in the fine print; just found out you CAN'T turn off 1-Click buy - not in the app nor Amazon's site. My helicopter bank sees fraud in every transaction, and freezes my card if I make more than 2 or 3 purchases in a row, it's a real hassle to unfreeze it, over and over (No. They won't put anyone on permanent white list). Obviously Bezos doesn't care about fraud, those with tremors or with paranoid banks. Can't really ditch Kindle; too many books, now. AAAAHHHHH!!
