Ah, I am trying to decide to buy cheaper older unopened ones or pay more
for the new ones.

How old?

Like a couple years old.

I've seen HP inks for wide format printers that were
still perfectly good after sitting on the shelf for 6
years. I've used 2 or 3 year old Epson carts with no
problem. I've heard of many others with the same
experience.

Still, it boils down to how critical your prints are.
If you are making posters, brochures, menus, and the
like, that bascially are short term... try it and see
if it works.

For printing archival photographs for an exhibition, I'd
stick with current OEM inks.

I got a HP's e-mail about this when I asked:

I finally got a HP to e-mail me about this:

"... You need to know that the expiration date is
related to an unopened cartridge, but after that, I
would like to know when did you open it, also be aware
that this cartridge is almost two years old in your
possession, we do not advice tothe customers to have
cartridge storage for more than 6 months, even this
could be not advisable, but some customers do that.

Regarding the RMA, well, it will not be possible for me
to offer you that, it is not an option..."

Is this true? Thank you in advance.

That is all true. Just be aware that they do NOT say
anything about whether the ink is good for 2 years or 10
years. They say they don't advise keeping it that
long... mostly because they are in the business of
selling ink. If you throw away any ink that is 2 years
old and buy new ink, it's good for HP. Not so good for
you...
