The problem is that they don't always have the same stuff every visit. Car park can get a bit tricky. Good photo service. We love the dried mango, and rack of lamb. Mushrooms, and bread, always super fresh.

You can save heaps here. Almost anything from toilet paper,computer supplies, frozen food and really good quality meat and veg. You have to know your prices as not everything is cheaper and unless you do a $400 shop it may not be worth the time and petrol to go there.
If you and your friends are organised you can save heaps.

For big bulk items costco is great and can save you a lot. But you have to have the room to store it! It's a really fun trip and I enjoy walking around and looking at everything they sell.

For big families or if you're planning a party or event, Costco is great because you have to buy everything in bulk. I have found the prices to be generally cheaper than the normal shelf prices of Coles or Woolworths. But if you buy at Coles/Woolworths when things are on sale then you can get them cheaper than at Costco.
On the weekends they have staff giving out samples of some of the products which is great bceause you get to try things you wouldn't necessarily buy before hand.
Costco has a great range of ready made meals in their fridge section as well as a huge variety of fresh produce. They don't stock several brands of the same item though so you often have to make do with the brand they stock if you want a particular product.

Putting aside the $60 membership, I think Costco is great value! They have everything you need for a house, although not a huge range of brands.
The fresh food is great quality and I buy and freeze what I don't need. Cleaning supplies are cheap, but like everywhere you have to know the prices elsewhere, sometimes it's only a few cents or dollars depending on the product.

I love the kitchen wear, they always have things I've never seen and always buy. Like the chopping board with a colander in it!

Weeknights are best for quietness, they're open to 8 or 9 from memory. The staff are helpful and happy to help if needed.

A great place to shop. You have to be a member and can purchase this for about $60. You have to know your prices, but there can be some real bargains. They have everything from TV's to stationery to clothing to food. They have their own butchers, bakers, pizza makers and they are all behind glass so you can watch what they are doing. They have great fresh produce, meat and bakery items, as well as frozen foods. You mostly have to buy in bulk, but it's easily put away or in the freezer for later. I really like this place. I've been there 3 times now and they have had some different things around the place each time. They also do cheap photo printing 9cents per print if i remember correctly.

Costco is worth the $60 membership just for the "larger than life" shopping experience! (Even the trollies are super-sized!)
Definitely worth going to for:
- Meat and seafood: reportedly very good quality and reasonably priced (but in min. 1kg serves)
- Toilet paper: I always stock up here and buy 60 rolls at a time (!) - one less thing to think about buying when I'm at the supermarket - plus very cheap
- American junk food: huge range, if you're into it
In terms of the prices - as another review stated, many item prices are the same or not much better than what you'd get in a Coles or Safeway catalogue. E.g. I bought 14 bars of Dove soap at Costco thinking that I'd picked up a bargain, only to see it listed at the same price per unit in another supermarket's catalogue (I could have saved myself from storing 13 bars of soap!) Think about your storage space at home before you make your purchases.
The range - they generally offer their own brand (Kirkland) + one or two major brands for each good, and that's it.
Best time of day to go - before midday, weekdays - very quiet, no queues.
Parking - first 2 hours is free
Again, as someone else said - a great place to visit if you're planning a large BBQ or event.

I have visited this food court twice when hungry and each time left without purchasing anything. It offers oversized, full of fat and preservative food that I can say no too. The only cheap aspect was the dining area at the end of the checkouts. Easier and healthier to walk out across the plaza to the variety of food vendors in the rest of the Docklands precinct or in my case wait till I got home and cook some of the fresh ingredients I had purchased at costco.

Costco foodcourt open to public, just need to register for visitor pass and you can enjoy the food at costco...real good food with great value. not much of selection but cheap

Approximate cost: $3

Joined up and visited Costco 25/07/2010. Really didn't know what to expect. Waiting to obtain membership wasn't great. Joined on Internet before going there. Don't bother as you must still queue up being it was first time and had to get membership. Once served took less than 1 minute to obtain. I actually thought shop would be bigger. You must know your prices so make sure you research before going. Some items were cheaper but some items were not. If you are only shopping for two as we have no kids, it might be best to share with another family member to get bang for buck as everything is large or you have to buy an item and there could be 4, 6 8 in a pack. If we brought their vegemite this would take about 4 years to eat as it is so large. There pizzas are fantastic. That big that it wouldn't fit in oven had to cut in half to place on two shelves. Quality of pizza fantastic. Very fresh. If you want to buy clothes there is no where to try on so you must buy try on at home and if it doesn't fit you must go back there. Good business sense to get you back in but pain in backside for shopper. You must queue up at registers and for 11.30am Sunday not all registers open took us at least ten to 15 minutes to get through. If you had to cater for a party then this is the shop you must go as you would save heaps. If you are just browsing and wanted to have a look like us, then I suggest to you don't join. I thought service would be great especially because it was Americans and they say they have the best service, you will be very sadly disappointed. Very hard to find help on floor and prices were not on every item which become difficult and time consuming just to ask people for help. We will not join up again. Heaps of improvement is needed to suck us back in.
