Very good price on this staple food item for those who must eat Gluten Free or Wheat Free. About £1.86 in major supermarkets (if stocked). A good all purpose substitute for ornery wheat flour - good for cakes, batters, pastry and all sorts.
The downside is the carriage cost - but free for orders over £35. The site has a good range of gluten free and other 'free from' foods including speciality flours (soya, potato, chestnut etc.). So if you are coeliac then you might easily get a £35 order.
I have ordered before and found them very good.
