Let’s delve into the world of Costco, the warehouse club giant, to explore a number of smart choices that will make your shopping experience all the more advantageous.

What to buy at Costco: For all future or current addicts

In-store payment is by debit card, cash, Costco Shop Card or any Mastercard credit card.

You can also pay indirectly with a Visa credit card. Simply go to costco.ca and purchase a Costco Shop Card to pay for your purchases at the warehouse.

Costco isn’t coded like a grocery store. Costco is considered more of a “warehouse”, so it will give points in the “Other” category, with the lowest credit card accumulation.

The best Mastercard credit cards to use at Costco are :

Card Point Redemption
National Bank World Elite Mastercard 1 NBC Rewards point / $1 purchase Travel
National Bank Platinum Mastercard 1 NBC Rewards point / $1.50 purchase Travel
BMO Ascend World Elite Mastercard 1 BMO Rewards point / $1 Travel
Rogers World Elite® Mastercard® 1.5% cash back on all purchases Cash Back

 

50 items to buy at Costco

Here are some suggestions for foods and items worth buying at Costco to save money compared to prices elsewhere.

Fresh products

  • Frozen fruit and vegetables
  • Bananas

10 things not to buy at Costco

Based on my experiences as a Costco shopper and prices elsewhere, here are some items that may be worth buying outside Costco.

  • Seasoned roast chicken 1.2 kg, $7. 99: You either like it or you don’t! Fat, undercooked, too salty… At this price, try it at least once to find out. It’s the best price for a roast chicken, but the quality leaves something to be desired in my experience.
  • Fresh fruit and vegetables: Unless used within a short time, these large-format fruits and vegetables spoil quickly.
  • Soft drinks: When you’re on the lookout for certain specials in grocery stores or liquidation centers, it’s cheaper to buy them in smaller outlets.
  • Laundry detergent and tissues: Pharmacies and grocery stores often have better prices, especially when there are promotions.
  • Kirkland toilet paper: The quality of this product has unfortunately declined in recent years.
  • Cans: There’s a chance of a better deal elsewhere, as they’re more expensive at Costco.
  • Sunscreen: The choice of sunscreen available in the warehouse is limited. The best cream will depend on your skin type and whether you prefer a mineral or chemical sunscreen. Keep a close eye on whether the ingredients are right for you, because a sunscreen shouldn’t be based solely on economic criteria.
  • Items you don’t need: It’s so easy to get carried away the first time (and every visit thereafter…) at Costco. We go in to get bananas and come out with 10 other unexpected things, all the while forgetting about the bananas.
  • Spices: Even if the price and quality are excellent, you need to think about how long that huge jar of spices or box of dried herbs is going to last. Over time, the flavor will be altered.
  • Gold or silver bars or coins: Costco sells 24-carat gold bars and .9999 pure gold or silver coins in one or more ounces. They are slightly above market value. But if you have an Executive membership card, you’ll get 2% back, as well as points or cash back on your credit card. You need to have the right insurance at home, the right storage and know exactly where this purchase fits into your investment strategy. So it’s not for everyone.

The difference between Costco warehouses and Costco for business

Large-format products can be found in both types of warehouse. Individuals and families can also take advantage of Costco for business discounts, even if some items are not similar.

Mondays, Tuesdays and Wednesdays are usually the best times to shop in the most peacefull way at Costco.

To avoid a cart hitting your ankles or a parking lot overflowing, go a few minutes before the official opening or 30 to 45 minutes before closing. Also, avoid weekends or the eve of statutory holidays, when everyone is in a hurry.
