Coles Supermarket

This is now located on Station Street and the move have greatly increased the store size.
The aisles are now wider and the selecting of goods is much better.

Approximate cost: $200

Coles in Subiaco is one of the few supermarkets that is open on Sundays (even though it's only open 11-5). They also have late nights - until 9pm, which makes them a convenient store for me to shop.
Plenty of parking, and the good value products you expect at any Coles supermarket.
They also have a deli for your more luxury cravings.
