Query: Who bought all the Benefiber?

I have been a decade long user of Benefiber because I don't always have time to sit and eat as healthy a meal as I should. Benefiber helps me get the fiber I often don't have time to from fruits and veggies. But I think there is something rotten in, whereever Benefiber is being shipped from. In the last 3 months I have watched the price of this TRIPLE. YES, TRIPLE. Anyone have any idea's as to why? I have asked Amazon but the only explanation I get is, "Seller's can sell for whatever they wish." I pointed out that this is PRICE GOUGING and that Amazon has a duty to it's customer's to not let this happen. Seems that isn't something Amazon worries about anymore.
