🧀 Cheese & Dairy: Best Deals at Costco

Costco is my go-to for cheese. The prices are unbeatable compared to regular grocery stores, especially if you love stocking up on high-quality, grass-fed, or specialty cheeses.

• Dubliner (grass-fed sharp cheddar): About $10/lb at Costco

  • Compare to Sobeys: $23–$26/lb

• Saputo Sliced Swiss: About $2/100 g at Costco

  • Compare to Sobeys: ~$4.50/100 g

• Kirkland Cream cheese: $10 for 4 packs ($2.50 per 250g)

  Compare to Sobeys store brand 4$ per 250g

  
  

If you’re a cheese lover, these are definitely worth picking up in bulk.

💡 Tips for Shopping Smart at Costco

1. Compare unit prices with your regular grocery store—or other discount stores if you’re willing to buy “less fresh.”

2. Buy in bulk only if you’ll use it before it expires or if you have freezer/storage space.

3. Check seasonal deals—some items are only a steal at certain times.

4. Remember warehouse pricing vs online grocery: Prices in-store usually beat online listings, especially for smaller orders where surcharges apply.

5. Bring a cooler bag - for frozen items, meat and dairy. I use this one : [link here]
