Unfortunately they have gone up market as they have been discovered and the
packing on the shelf habit is waning

I blame the rise of re-usable shopping bags. The most common scheme I
see deployed is from till into one or more of such bags propped open
inside the trolley. Which is noticeably slower (for the till operator
and the queue) than bunging it all back in the trolley and using the
packing shelf.
