Although this doesn't appear to be on offer as such - I purchased these in-store yesterday because they were a lot cheaper than the Kellogs equivalent. Tasted today and they are equally as good if not better.
Looking at the ingredients they are identical with the exception of the whole wheat where ASDA is 75% and Kellogs only 65%.
Kellogs 750g at ASDA are £2.10
ASDA 1kg are £1
