Where to buy castor oil in the UK?

After going to every Boots in the area, a list of supermarkets and health food stores, I finally found some in a little independant chemist.

ETA: Boots also told me that it was difficult to get hold of and they had no idea if or when they would have any more in stock. Hmmm, I think I'll pop back to that chemist and stock up.
