Yes, storage is the biggest thing to consider. I have an American fridge freezer in the kitchen and a larder freezer in the panty. I also have that pantry, We are on a 2% cashback account and our Costco has the petrol station. We have been members for 20 years.
To give you an idea of pack sizes Kirkland toilet roll is a pack of 40, tinned tomatoes 12 tins, tuna 12 tins, tortilla chips 1.13kg bag, frozen salmon (fillets are twice the size of the supermarket) 7 in a bag. White bin liners a roll of 100, black bin bags a roll of 90. Tissues box of 12.
Some things are great quality but are not cheaper than a supermarket. There are things that we get every time like Kirkland cheddar which is massively cheaper than the supermarket. Every few years I print off the master shopping list and write down all the prices and compare at home.
Their rotisserie chicken must crack cocaine in it because it is absolutely delicious. Clothing is good, they sell things like Skechers trainers. Kirkland batteries are I believe made by duracell.
We buy the vast majority of our chicken, pork, minced steak and fish from there. If fresh we portion and vacuum freeze. Off the top of my head, we buy their wraps, eggs, milk, chicken tenders because they are strips of chicken breast, vitamins, shampoo, conditioner, hummus, dettol laundry and everything else I have mentioned.
Their guarantee on electrical goods exceeds the manufacturer's. We had a tv switch die after almost 5 years it was repaired for free. Customer services rang me afterwards to check on the company they sent, were we happy?
If you know someone who has a card and you can look around before you commit that would be good, if not take a punt but remember your boot is only so big and you have to store it all somewhere.
