I don't believe there was a shortage.
My take on these 'shortages' are the shop managers. They find that people are looking for the longest dates on produce and select them, leaving the shorter dates on the shelf. Before the shorter ones go out of date the managers pull/hold back the longer date ones then say they are having problems getting supplies. Shoppers then panic and buy all the short dated stuff whilst the shops hold on to the new stuff for a few days. When they appear on the shelf people buy them in bulk in case they run out again.
It's called psychological salesmanship and happens all the time.
Why do you think they have special offers displayed at the ends of aisles? Because as you turn the corner you will look sideways to see what you are passing. They always had sweet racks by the tills, so the kids would pester their parents to buy some. The parents, trying to pay for their shopping, would often as not say, "Go on then, put it on the belt quickly."
