We are clearing our stock of Xanthan and have reduced it to just £2.99 per kg. Thats enough for over 70 litres of gunge. This has to be the cheapest gunge out there so nows the time to stock up.

just wondering how will the packets be shipped? plain box, no hint to contents? seems like too good a deal to pass up.

Yes, it comes in a plain white Jiffy bag with no markings.
