I am retired, and have time available
Probably like many British towns now my local town centre has several bargain/saver/discount sort of stores. I had shopped in all of them, but decided on one afternoon to visit them all, and pay more attention to the sort of food each one sold
I was thinking along the lines of perhaps one will be good for coffee, another for canned food, and so on
Well, I did that and mentally noted those I would visit again for certain things, and those I wouldn't bother with in the future. You can get good buys if you are selective and keep your wits about you
But what did dawn on me was that they all had large areas of shelves devoted to sugary foods - biscuits, cakes, sweets, chocolate, and other confectionery
