AA & AAA Eneloop Rechargeable batteries very good deal.
The Roast Chickens (ready to eat ones not the ready to roast ones ) $6.99 for a size 14 (bargain).
Petrol & Diesel around $0.10 to $0.40 below current other retailers prices per litre with the Premium 98 probably the best saving per litre. If a regular filler upper as @PhilT notes you will pay your membership off in savings quite quickly.
Fruit and Veg variable in whether a saving or a extra cost money wise. Eg currently 1 kg Vine Ripened Tomatoes $7.99 a kg (prepackaged in 1 kg lot) & at local Greengrocer $3.99 a kg loose but 850 g Strawberries at $7.99 (special normally $9.99) compared to $2.50 per 250 g punnet (so a current saving of about $1.00). Some items you have to buy multiple so even if cheaper when comparing single item price you wouldn’t eat the amount in time to achieve the saving eg Cucumber, what we call Shallots but some call green onion or spring onion & large bags of green salad leaf.
Toilet paper not a saving on what can be bought elsewhere.
Washing powder variable but currently trying the Kirkland one which was a saving of at least $10 but we still can’t say we have fully evaluated both economy and cleaning power.
Vitamins and others as @PhilT notes are variable but mostly find them as savings eg the lens cleaner wipes are a super bargain, the protein powders not so much.
Meat we save more elsewhere than at Costco but if it was a choice per kg between Costco and normal retail stores the price would be best at Costco hands down, just have a large freezer to store the excess.
Bread normally dual or multipack retail brands, cheaper per loaf but again have a freezer to store the others. If buying the store brands from ALDI, Coles or Woolworths you can save a little sticking with them.
The Choc Mud cake with a diameter of about 40 cm at $25…yeah baby but off the diet atm but drool marks always follow me afterwards…same for the Blackforest cake, the Cheesecakes, the mini apple turnovers, the pastries, the croissants, the Birthday cakes, the Giant Iced Donuts (about 30 cm diameter). Lets just say temptation alley. Fresh Bagels, bread rolls and buscuits again very good deals but need freezer storage.
Next time I am in store will run the camera on the phone down a few aisles to get a running price and choice video for you and will repeat a few times over a couple of visits, just have to put a reminder in to myself to do it.
Tyres seem a better price than retail elsewhere.
Ready to Cook Pizzas are big like old style (20 years ago at least) family size. So if dinner for two is the idea maybe a little too big but pricing depends on the style (3 choices I think) but ranges from about $11 for the basic cheese to about $15 for the meat lovers one.
Coffins are a bargain…starting at around $399 for the Enviro one up to about $4000 or a little more for the ornate ones…I have the catalogue so will scan and send if you leave an email addy to send it to (feel free to pm me)
Artificial Grass, Sheds, Spa pool, Solar system cannot make a price comment on but happy to get the brochures for you.
Books to buy and read, seems great bargains to me but value may be variable to those well versed in the costs of the printed material.
Jewellery, TVs, iPads etc AV stuff eg headphones, and a whole slew of similar gear again I can’t really make comment on other than to say expensive to me but may be a great saving for the brand name you are buying. Currently the biggest screen TV they have in our store has a price tag of $18,000 so not my everyday just pop into purchase a very large screen TV price, I would need to save for about 20 years and sell the body parts I could do without.
Watch the moths enter the wallet as you leave the store…easy peasy to put a few items in and voila $100 plus bill in the blink of my not so very bright eye. I think that is why they have cheap eats after so you can rub that guilty feeling with the balm of a cheap feed…seems to work on a lot of people as they go smiling out the door $400 or more poorer as they do so every minute of every open hour.
I haven’t bought that crazy thing yet but there is still time and the wife willing it may still happen but as to what it is I have no idea yet as there are some crazy things to tempt the stocked up wallet. Now where was that battery powered 4 WD car again???
