I am one who has made a conscious decision to try to purchase groceries at Irish owned supermarkets (Musgraves, Dunnes) rather than non-Irish owned (Tesco). The owners of the supermarkets may well decide to spend overseas but, to me, there is a greater chance of the money recirculating in Ireland and locally.
It will have a minute effect but I am noticing too many small local-owned shops closing down. The effect on the streetscape is so depressing. The likes of Opera Lane with its chain store shops could be any city anywhere. No individuality or reference to location.
I will still visit the discount supermarkets. My decision will unlikely affect Tesco’s market share unduly.
It does take a long time for dripping water to make effect in a stone.
