Costco Crossroads NSW opened up yesterday (21 Nov). I've been told that the price of fuel at this store location is/was:
E10: 122.9c/L
Premium: 146.9c/L
By comparison, the cheapest premium fuel that I've been buying lately has been 155.Xc/L at my local Speedway; while usual Coles/Woolies were around 175c/L mark before shop a docket discount.
Hopefully Costco is able to offer these sorts of discounts on an ongoing basis and it's not just a store opening promo.
What about Diesel?
