Example Input: and THAT is  the problem. I order these by the case of 12 - and when they are good, which is over half the time they are the BEST kettle chip, THE BEST! and then I get a case of the worse - the potatos are mealy and old so I just throw them out and order again, expensive BUT when they are made with good fresh potatos they are the best - the last case is what prompted me to write this - the potatos were weird - like they were almost sour as in going bad - and I even wrote the company that makes them - SO if you want the BEST kettle chip there is try these and if the ones you get are NOT the best try again! I, myself am done ordering because it is creeping me out that they are using soured potatos and either not noticing or not caring.

Example Input: Trader Joe's Pomegranate White tea is superior to this tea. This is very bitter and perfumey. Maybe thats what you get when you brew whole leaves and stems . I found it repulsive.
