We have a Costco membership..I love it! You can go in with a member and browse or if the member is willing, you purchase and they put it through it for you, you just give them the cash.
We buy, baby wipes, tinned tomatoes, passata, tim tams, toilet paper, paper towel, tomato paste, kitchen scourers, dishwashing powder, the blue wipes, foil, glad wrap, sultana's, cat litter, some lollies.
It sells alot of American sweets as well. I saw a lady with a trolley full of butter, she freezes and it and says it's the best quality butter she has had for a long time.
I know of people who share a membership, so they go halves and shop together and split the bill after checking out.
They also sell clothes, Osh Kosh and other brands. If you buy moisturisers like Olay, they have that as well. It's all branded products, unlike Aldi which is there own brands mostly.
I never get out of there without spending at least $200..I have been at the checkout when I heard someone's tally at $1000.
You need to have an empty boot when going there
We bought our bar stools there as well...these were two for $90 and I have seen them at furniture places for $90 each.
Basically, anything you purchase at Coles or Safeway, Costco will 9 times out of 10 have it in bulk. A GF of mine bought a tray of lamb cutlets, they worked out at around $1.50 each I think, maybe less, I purchased some at the butcher today for my kids dinner and they were $2.50 each.
