Bit of research for ya... 
"The nature of marketing new products is that regional testing can lead to certain items never reaching the greater mass of the public. Evidence seems to indicate that there may have been experimentation with a 'Flavour 'n' Shake' product in the 1980s; but the test release failed to show positive responses and the product was dropped. It seems likely that because the manufacturer was based in Leicestershire, UK, the experimental product never saw the light of day outside of the Midlands region.
The experiment took the simple blue bag of salt and replaced it with a flavouring that could be added in the same fashion described above. For those with a taste for adventure this meant that collecting different bags of flavouring would allow the creation of some truly tongue-pounding combinations that could be enjoyed with or without the crisps supplied."
Midlands region? Well we had them in West Sussex!
