All been said, we do tend to all buy from different places.
I buy my oatbran from H&B, esp when its on offer. Wheatbran too, which is allowed from Cruise onwards. HB is the cheapest place.
there are few products that are zero fat in the UK, and the uk print of the book kind of mentions this.
Quark is the lowest cream cheese type product, 85p in asda (rollback), similar price in Morrisons but slightly smaller tub.
I buy Aldi Low Fat Greek Yogurt....and make my own lo fat natural yogurt.
