All the potatoes I put into store last year, have been sprouting for some
time now, whilst it doesn't seem to stop me eating them, it's a nuisance
to
find when I go to bring them into the house that I'm having to pull off
sprouts 3 or 4 inches long.

They are stored in boxes, covered with sacking, so no light can get in.

So, is this common, or am I doing something wrong?

The potatoes in the supermarkets don't seem to have this problem.

Temperature as well as light can induce sprouting. Supermarket
spuds are probably maintained at a specific temperature which
inhibits sprouting but doesn't damage the tissue of the potato,
as would exposure to frost etc. They probably only require a
few hours at the higher temperature for this to irreversibly
trigger the sprouting mechanism. After purchase, supermarket
spuds will probably start sprouting after a week or so as
well.
