Schwartz Flavour Shots

Does anyone buy the Masala curry one as I just can't get them anymore,every supermarket I go in doesn't seem to stock them any longer,I've tried several Asda's Tesco,Morrisons & Sainsburys & no luck.Does anyone know a supermarket that stocks them please?
I'm going to email Schwartz next as these are my absolute favourites and I will be most upset if they are discontinued!
