I have avoided writing about consumer response to the recession because there is so much data out there and much of it is useless or simply common sense.
One that that I think is interesting though is the changing trip types. I think this is the key to understanding consumer changes. And I note that Wal~Mart is focusing on this in its new US commercials. These are clearly encouraging shoppers to combine trips - and in particular the grocery trips.
Target take another approach but also tap into a clear consumer trend - staying in. They are advertising DVD players for "the new date night" and hair clippers for the "new hair cut" etc.
