This chart is based on what I spent on my last three weeks of grocery shopping. I spend £15-20 a week on groceries. I suspect that I am fruit-and-vegetable heavy and bakery light.
By the way, it was not my idea to put two decimal places on those percentages. Of course I can’t state my grocery proportions to four significant figures of accuracy. OpenOffice did that automatically and I couldn’t figure out how to change it. I don’t know if it’s because OpenOffice Calc is not user friendly or if I’m crippled by Microsoft Excel brain.
