I've heard that the rubber "suspension piece" (for want of proper name) in a cartridge can dry over time.This would be a problem if purchased for use years down the road.
Are there any storage methods to prevent?

"In fact, I would be more leery of storing a cartridge long term without ever using it (NOS) vs using a cartridge lightly over a long period of time. The latter probably would better preserve the compliance of the suspension."
+1 I read a post by a MC cart maker. He had bags of 30+ yr old carts that were given to him. He said he never saw one with rubber damper failure. It was always the suspension wire that went bad. They use synthetic rubber compounds and it doesn't take the abuse of a car tire.

Rigs that is used to seal food in plastic bags. I can't remember the name of the thing but it comes with plastic bags and a thing to pump out the air and a heat thing to seal the bag.
They are usually used to store food in the freezer for long periods of time and the vacuum ensures better long term storage. I suppose that this would be good for long term storage of a cartridge also.
I would avoid putting it in the freezer. Just vacuum seal it and put it somewhere safe.

That is a great idea, provided the bag itself will not leach plasticizers or other compounds that may do harm. I would also avoid a really hard vacuum, to prevent the low pressure from pulling out slightly volatile compounds in the rubber parts.
And put the whole thing in the plastic bag. That way you don't risk anything leaching to the cartridge and the cartridge is protected.
I almost bought one of these (I think it was around $20) but got sidetracked and never went back. I have a couple of cartridges that I have sitting in boxes that would probably benefit from this approach.
Maybe I'll pay Walmart a visit and see if they still have this thing.

I think it's like cheese and bread; both will age from within regardless of how you store them. But with cartridges, it's a crapshoot. I have some 30-year-old used cartridges that sound fantastic. In fact, I would be more leery of storing a cartridge long term without ever using it (NOS) vs using a cartridge lightly over a long period of time. The latter probably would better preserve the compliance of the suspension.
Like a car (or cassette deck) the longer it sits the more problems it may develop.
Rubber parts need to be at least occasionally flexed to help maintain their integrity.

A gas tight sealed container (mason jar perhaps) will minimize exposure to only those contaminants that you seal into the jar (ozone is the primary concern) instead of exposing the cartridge to constantly renewed sources of contamination. Hifitommy also proposes a possible improvement on this method.
One could use a can of nitrogen gas to displace some of the initial oxygen rich air that you seal into the jar in the first place (can be bought at wine stores), but, I don't know if there are possible other contaminants in those nitrogen bottles that could also be harmful.
I would just seal it up in an air tight container and not worry too much about it.
now that nitrogen is used in tires (a big advantage) you should be able to buy it and put a cart in a jar then top off with n2. no oxidation.

You can keep it at my house.
You beat me to it.
I would imagine keeping it in its original packaging in a room that the temperature doesn't vary through the year (or day), would be very important.
No sunlight, of course. I think exceedingly dry OR humid would be deleterious.
I have a Supex that "seems" to be in great shape although I'd believe the previous owner did little or nothing to protect it. It was hanging on the arm (PA1000) on the Kenwood KD500 when purchased at a flea market. I listen to LPs quite often on that deck, with no signs of wear to the LPs; the sound is quite good.
