Right now, for a grocery store, that means they can put butter on sale that women will buy for Christmas cookie making, and market sprinkles and decorative sugar at higher prices (or with a coupon) to increase customer value. That MDA heart that you bought on Labor Day weekend helps assess the effectiveness of that sort of promotion.
I’m sure they’ll stay competitive in the future.
And from what I know, that’s less about survival, and more that they can’t expand horizontally anymore, and the new owners (the Albrechts both died in the past years) also want to expand vertically into other market segments.
Supermarktblog documents these changes quite well, IMO.
