The question is: How does one explain this anomalous phenomenon?
A small supermarket operator from Choiseul explained it in terms of "stock" and "time"! Indeed, his explanation needs validation. How fast is the turnover of stock?
While a free market economy is designed to generate profit for investors, shouldn't it also have built-in safeguards to protect consumer interests? If it does not, then we may well be encouraging a form of daylight robbery of the type which seemingly (and in my view) characterises the status quo - even in the midst of an "Oil and Gas" revolution which has resulted in the lowest gas prices in 12 years.
