How many shoppers actually have the time or the motivation to work such math out is an unanswered question (and maybe we should, what do you think?) but it shows what is possible given the right kind of motivation.
And how do the manufacturers feel if there are scenrios where-by the shopper is basically paid to take away their brand? (We'd love a comment from a manufacturer if you are reading this). Different for retailers, as we don't know the impact on this shoppers overall basket size, but still, for a premium brand it has got to feel pretty yuk to find the shopper is paid to take it home with them.
