More shoppers making the switch to discounters

Five times more shoppers are doing their main shop at budget supermarkets, Aldi and Lidl, than before the recession.

The main casualties of the switch to the lower price stores are Tesco and Superquinn, which are the main shopping destination for a third fewer customers than before.

Dunnes Stores is down a quarter on the number of customers who previously did their main shop there and the smaller chains are collectively down almost half.
