We planned to purchase a refrigerator on Amazon, so converted some rewards points (from Chase I think) into Amazon Bucks. Placed the order - and the vendor responded - Sorry - Out of Stock!! OK - what to do with the Amazon Bucks? Two brand spanking new i-Pads of course. Initially used to replace our Kindle devices, the use rapidly expanded - would not want to be without it. Never any "trouble" with it. We've had these for four years!
