While the chief absurdity is very clear (also mocked by Spitting Image - J.B. on a date: "You loved that steak? Good, I'll order another one!"), I am afraid that the intended idea may be that your memory about the ads of what you just bought will last as much as said goods.

Utter nightmare (unnatural obsolescence, systemic perversity, pollution...) but. I have met R'n'D who admitted the goal was just to have something new to have people want to replace the old, on unsubstantial grounds.
