Costco Comparison

Costco Price Comparison

 

The very first Coscto in Adelaide opened last month, and I was just about jumping out of my skin to finally visit the store earlier in the week, and of course eager to do some research for this Costco comparison.  I had no real idea of what to expect, so I asked for advice on our Facebook page.  The most common piece of advice was to know you prices, as not everything is cheaper than the big two supermarkets.  Armed with this advice, I headed in to eagerly become a member and start shopping.  Below is my shopping bill, along with price comparisons from Coles and Woolworths.

Hershey’s Chocolate Syrup 1.42L x 2 – $8.99

This is not an items either Coles or Woolworths stock so it’s not really something I can compare.  This will be added into the Coles and Woolworths total prices to keep the comparison equal.

 

Devondale Long Life Full Cream Milk 1L x 10 – $11.99

The Costco price works out to $1.20/L, Coles is $1.00/L (on sale) and Woolworths is also $1.00/L

 

Full Cream Milk Powder 1kg – $5.49

The Coscto price is $5.49/kg, while Coles is $9.35/kg and Woolworths is $8.99/kg, both Devondale brand

 

Arm & Hammer Baking Soda 6.12kg – $8.99

The Costco price works out to $1.47/kg, while Coles is $3.80/kg and Woolworths is $4.60/kg, both Mckenzies brand

 

Finish Concentrate Dishwashing Powder 1.5kg x 2 – $26.99

The Coscto price works out to $9.00/kg, while Coles is $11.00/kg and Woolworths is $11.90/kg

 

Sunbeam Sultanas 1.5kg – $8.39

The Costco price works out to $5.59/kg, while Coles is $6.67/kg (on sale) and Woolworths is $6.60/kg

 

Sorbent Long Roll x 40 – $22.98

The Costco price works out to $0.21/100 sheets, while Coles is $0.39/100 sheets and Woolworths is $0.29/100 sheets

 

Costco Total = $222.93

Coles Total = $335.02 ($112.09 more than Costco)

Woolworths Total = $309.96 ($87.03 more than Costco)

 

As you can see from the totals above, the savings were pretty significant.  When working out the Coles and Woolworths unit prices of each of the above items, I used their online store prices, compared the same brand wherever possible, compared the biggest product sizes that offered the lowest unit price.  I also used sale prices rather than full retail prices, as I wanted to get a snapshot of the savings Coscto would give me compared to walking into Coles or Woolworths now and buying the same items.  I worked out the total by multiplying the unit price from Coles and Woolworths with the package sizing from Costco.

 

There is no doubt I will be continuing to shop at Costco, but given the distance it is from my home it would only be a once a month type of trip.  I’m already loving having the bigger packaging sizes in my fridge and pantry, and loving the less frequent trips to the supermarket that come with it!
