I'm interested to hear what others think of Costco. I, myself haven't been there as yet! We are considering it when the new one opens up down the road from here near Moorabbin airport! I have heard from others that its great for buying in bulk, if you have the space to store such things, which I will have soon! I don't think that I would buy the fruit and veg though as I am very happy with the market place that I buy from now that is both great quality and a lot cheaper than the supermarkets and last so much longer. I might have to try out the one in Ringwood, just to see what its like, so I know whether its going to be worth it for me, although I have a few friends that have said that they will split some of my purchases with me!
