As Dakota said, DNA is really stable. Usually in the > 100,000 year range on ice with nothing special added.
People have tested this by calculating a rate of hydrolysis and extrapolating.

I think they get high profit margin off this. Extraction is cheap and
it looks like they lyophilize the DNA and stick it in a sealed tube in
a steel cylinder.
The target customers are those who probably think they can clone
people in the future. Or maybe use the DNA for sequencing in the near
future (when prices go way down) to determine any genetic diseases.
