Fluctuations in cost

for the same standard items across parts of England ...

in Kernow shopping a grocery shop could be more expensive for me  .. In Crewe in Greggs it is 10p less than in Dartford ... 

this I am remembering again this divide within a country ... thankfully when I am tired thy Cornish lilt comes through rather than my city slang ... I blend in although the way I say ta ra gives it away ...
