I prefer own brand goods.But then I hate hype and I found that baked beans and toilet rolls don't differ by much.I always but the cheapest savers choice as well..Why pay 35p for tinned tomatoes when I can get them for 18p in the budget range?
The only thing I make a fuss about is veg and meat.Saturday market for the former and a trot to the local butchers for the latter.Supermarket meat(apart from Waitrose) is crap.
