Unsalted Crisps

I much prefer unsalted crisps, however I am having real problems buying them locally.

True I can buy Smiths (actually Walkers) unsalted Salt ‘n’ Shake crisps, but I much prefer the traditionally cooked crisps you can buy.

In theory Tyrells, Kettle and Burts make unsalted crisps, but though my local suppliers have other flavours they no longer stock the unsalted versions.
