I recall a number of "shortages" at or about that time. By and large they weren't genuine shortages but caused by housewives, many of whom were still steeped in wartime attitudes, hoarding commodoties which were rumoured to be in short supply. These included, from memory, sugar, flour, coffee, butter and even toilet roll.
One commodity which was in genuine short supply during the time of the miners' strke was coal, much of which was reserved for electricity generation. Even that didn't prevent phased planned power cuts on an area by area basis the only upside of which was that you might be fortunate enough to be spared two or more episodes of Crossroads every week.
