Dave's insanity sauce: Does anywhere sell it in a shop?

[PeteMorris]

I've had a bottle of Dave's insanity sauce for quite a while now, and it's almost gone now.

 

Does anyone know (for definite) somewhere in Sheffield / Rotherham / Barnsley that actually sell this product? I can't seem to find it anywhere.

 

I don't want looky-likey, or tastes-the-samey type stuff. I don't mind the variants, like Dave's ghost pepper...etc.

 

Yes I know I can buy it on line, but that's a bit of a pest, and quite expensive, if you add in the postage.
