Cheap Asda flour

Asda are selling white bread flour for 50p a 1.5kg bag, which is much cheaper than any other strong flour I have seen. It also contains Ascorbic Acid (vitamin C) as a flour improver which may be to make up for it having a lower protein (and hence gluten) content than other strong white flours. For example, it is 11% protein compared to around 12% for other strong white and almost 14% for very strong white flours.
