salt shortage

[ffutures]

I can't get hold of granular dish washer / water softener salt at the moment, and I need it for home AND two dishwashers at work. Waitrose don't seem to have it, the local Tesco doesn't, anyone seen it on sale anywhere recently (pref. central London)?

I presume that production facilities switched over to salt for roads etc. for a while, but it seems odd that there continues to be none avaialable for dish washers.

Panic over - someone found some in Sainsburys and bought a couple of packs in.
