IT'S EASY! Or it would be if Marketing didn't fannydangle about with their categories a bit. I have tried to explain the sekrit marketing jargon in the poll below.
I will not be doing anything so fancy as making it viewable to none or screening answers but I will add up the MARX at some point.
AMBIENT BAKERY (this is bread and cakes basically)
BEER AND LAGER (we are talking the "off-trade" here i.e. canned and bottled)
BISCUITS (beware this may be 1xTRICK QN)
CANNED GOODS (meaning food not drinks)
CHILLED CONVENIENCE (this is cold meats, chilled ready meals etc)
DAIRY (all dairy i.e. milk butter cheese yog)
FROZEN PREPARED FOODS
HOUSEHOLD CLEANING (includes laundry and washing up)
SAVOURIES (earth name: crisps)
SOFT DRINKS (includes fizzies and juices - diet and regular brands counted differently btw)
The other category not in the poll is WINE - by all means give yr answer to this one in the comments box as a TIE BREAKER. It is a bit of a mentalist category, though.
You could probably google the answers but I think I'm asking you to waste enough of yr time as it is.
