These were my chips, and I ate them because I was pretty sure they would still be fresh.
It may be hard to read this part, but amazingly they have no preservatives.
I’m afraid I’m not following.
100 year chips! 
- 10
Oh, I read that date, like, 20 times
trying to figure out what the deal
was and still missed it. Now I get it.
Yeah, that would be good in a bomb
shelter.
oh dear…higher math
millennium chips
A great snack while watching TV.
Sometimes I notice that things aren’t really as . . . fresh . . . when they’re that close to the date.
Miss Vicki’s chips are often a little stale within a month or two of it. How were those?
Yeah, I come across chips/crisps like that from time to time.
“Still as fresh as ever they were!” 
Yes Lamby, that would have been a concern if I planned to eat them in June 3009, but I may not live that long,
even with a diet carefully full of antioxidants.
Actually, what I think this really reveals is the weird way my mind works. Notice that lots of people automatically read that date as July 30, '09, whereas I looked at it and thought wtfizz? What a silly misprint! Only after I shared it with one of the girls did I catch on that it did not mean to say 3009. Yes, I kind of have trouble with reality that way, sometimes.
most bagged chips are slated to have a shelf life of 6 weeks (although if packed under nitrogen can probably go 3 months). Pringles shelf life is 18 months. But there’s always the chance of a bag or can being a “leaker” and it will go rancid in a lot less time - usually 2 weeks, faster if there’s a lot of heat or light around.
fwiw, they were perfectly fresh.
I suspect the fact that they’re less than 50% potato aids their longevity:

So, I am to assume that you haven’t developed any odd side effects from eating them, like, say, a second head or bats wings?
Thank you no. My one head is inadequate enough.
OTOH, we do have at our house (to no one’s great surprise) discussions about what would be the best type of wings to have, and I have always opted for bat. But I don’t have any.
That’s a really cool thing to have a discussion about 
I wouldn’t mind a pair of wings. But they’d have to be Faerie wings.
The misprint on the bag of chips was rather funny. I wonder if you had put them away somewhere, with strict instructions not to open until 3009, what kind of compensation could be had from the company if you complained about the lack of freshness upon opening. Not that you would ever know, but anyway…my mind is working funny today. 
Go on, Izz, make it easy for them, why don’t ya… 
Not me. My mind automatically supplied
“2009” without ever noticing the 3 at all.
I guess I took it in as a whole without
breaking down its parts. And yet I still
can’t speed read.
Jen: Wings?! I don’t have wings!
Kira: Of course not. You’re a boy.
I’m not in Snacks any longer, but they were more than 50% for quite a while. It’s wasn’t cut up pieces of potato, but potato flakes, and granules (or flanules as we called them). With cost issues potato supply, and other things, the corn or rice was added to help with the sheeting of the dough, and crispness and doneness of the chip.
What aids in the shelf life is several things - “clean” oil that is watched constantly for the peroxide level, and the can itself which enables a much better seal for packing under nitrogen. What makes a chip (or any fried food) go rancid is a combination of heat, oxygen and light.
Oh…right 
Maybe they won’t notice…
