You can't use any of it as an A choice as A is for milk and cheese only. You might be able to take 6 syns off from the Original flavour and use that part as a HEXB, so it'd cost you 1 HEXB & 3.5 syns (provided the content is all the same as it is in the sachet version, which I dont know). The other flavours are not HEXes.
