I just read an article in the Wall Street that said that P & G (Known as "Proctor n God' in their home town) was considering dropping Pringles as being a "Slow growth product". Duracell batteries & Folgers Coffee were also mentioned as possibly being "on the block".
So far, this is only a "from an un-named source" rumor, but if you like to carry Pringles on your hikes as a tasty snack that is in a neat & sturdy container, it's something to keep an eye on.
FYI: Pringles are a double duty item; you can eat them, or start a fire with a Pringle or 2 as tinder. Yep, they burn
History lesson: Pringles were invented by Mr Fred Bauer, who still holds the patent on them. I think it was in 1956 that he invented them (& the can they come in) as a engineer / supervisor for P & G.
