TOTALS

Now that we've compared and broken down the prices for each of these products, let's get into the totals.

Here are the total costs for the 11 items before tax at these grocery stores in Canada:

• Costco: $165.79
• Loblaws: $93.37
• Walmart: $74.35
• Sobeys: $140.17

Costco has the most expensive basket of Christmas dinner staples, followed by Sobeys, Loblaws and Walmart.

The total cost before tax is $91.44 cheaper at Walmart than it is at Costco!

You might expect Loblaws to have the highest total since the store has a reputation for being expensive.

But that's just because the products at Costco are bulk-sized, so the price tags are bigger for most of the items.

When the cost is broken down by how much of the product you get, Costco isn't the most expensive store.

Here are the "price per" totals for each store:

• Costco: $11.80
• Loblaws: $14.30
• Walmart: $16.44
• Sobeys: $18.79

So, the most expensive "price per" total is at Sobeys, followed by Walmart, Loblaws and then Costco.

The "price per" total at Sobeys is $6.99 more expensive than the total at Costco.

If you want the cheapest basket total, you can get that at Walmart stores in Canada.

But if you want the most bang for your buck, that's at Costco. So, you might want to use your membership or use someone else's to get Christmas dinner staples at the wholesale retailer.
