No one should have any loyalty to any supermarket these days
You go where you get the best deal and the best product
We find IGA is good for variety if there is one near you
But we find that our buying is basically the same things and as retired people we do not need that much and can afford to buy in bulk when price is to our advantage
Certainly if you are lucky enough to have an independent store near you the range is usually superior to Coles and Woolies which are two stores that we stay away from where possible
