Costco gives you access to bulk and discount purchases that can help you unlock the true value of your membership. However, some people don't love shopping in bulk because perishable items can spoil quicker than they can enjoy them.

That's why we've come up with a list of must-have items you should definitely consider picking up on your next Costco run that won't spoil but will absolutely save you money.

Editor's Note: Prices may vary by location and can change over time.

We all need trash bags, so why not buy a big box of them that can last you a month or more?

You can buy 200 13-gallon garbage bags with Costco’s Kirkland Signature brand, which is normally priced at $19.99.

Olive oil

Olive oil is a must for many people, and high-quality, organic extra virgin olive oil is often priced right at Costco. A 2-liter Kirkland Signature brand bottle costs $25.99.

You’ll find a number of olive oil options, including some that are cold-pressed to ensure freshness. Others can be traced to Italy, which means you know where the olives are coming from and that they're high in quality.

Oatmeal

Costco carries oatmeal products in both individual servings and much larger containers.

Buying oatmeal in bulk is likely to save you money on a breakfast food that can last a long time. And don’t overlook the breakfast cereal deals Costco offers as well.

Whether you prefer K-cups or a big container of coffee beans, Costco offers both. In addition to coffee, you can also pick up a variety of creamers to go with it.

The store stocks several big coffee brands, including Tim Hortons, Starbucks, and Folgers. If you want to save even more, consider the well-respected line of Kirkland Signature coffee products.

Canned foods

If you want to stock your pantry with high-quality canned goods at a reasonable price, check out the wide range of products available at Costco.

Favorites include Kirkland Signature-brand chicken breast, green beans, albacore and light tuna, and a lot of beans. Many of Costco’s canned products are also organic.

Laundry supplies

From Tide to Kirkland Signature products, Costco has a huge lineup of laundry supplies.

The retailer often carries bundles or larger-than-normal sizes that help reduce your cost. This is especially true with laundry supplies since everyone has to do laundry, and you're not very likely to have to throw any out because you didn't use them up. 

Gift cards

Another great Costco hack is to buy gift cards at the retailer for a discounted price.

While you are at the warehouse, pick up gift cards to places you know you'll visit in the future. For example, Costco offers a range of restaurant gift cards, often at great prices below the face value of the card.

Looking for two $50 gift cards to Macaroni Grill for just under $80 total? You'll find them at Costco. You can also find discounted movie, travel, and retail gift cards, among other types.

Diapers

If you're a new parent, you already know that you can't have enough diapers and wipes. Buying in bulk can help you save money.

You can find a range of brands at Costco, including the Kirkland Signature brand, which can be much cheaper than name brands. You may want to check out the discounts on baby formula Costco offers too.

Vanilla

You don’t have to be a big-time baker to appreciate the high quality and competitive price of pure vanilla extract at Costco.

This is a natural extract and not vanilla flavoring, so you’re getting the true flavor straight from the bean.
