Spudshed Bentley is open 24/7 - perfect for shift workers and people like me, who like to avoid peak hour crowds.
This Spudshed is huge, with a fantastic range of fresh, cheap fruit and veggies. They also have a well-stocked dairy cabinet, fresh bread, deli meats, spices and the usual grocery supplies you would find in the major supermarkets.
Last time, I picked up a brilliant microfibre doormat for $6, so keep an eye out for random specials and promotions as well.
Approximate cost: $20
