8 Costco Hacks & Secrets to Save Money




As one of the world’s largest retailers and the largest membership-based grocers in America, Costco has made it’s impression on the market. But does shopping at Costco really save customers money? Yes. It. Does! While most deals are limited to members-only, this not-so-exclusive mega retailer has savings on everything from the kitchen to your garden.

While it’s true that buying less frequently and in larger quantities is one of the best hacks for Costco, the savings go beyond what you’re able to bring home in bulk. Not only are you saving money in the store itself, but less frequent trips to the grocery store will also save you time and money! And when you shop online with Piggy by your side, you’ll be able to save more and earn cash back without lifting a finger.

If you’re ready to discover the secrets of Costco shopping, here are some of the best Costco tips we recommend for every money-saving fanatic.

8 Best Hacks for Costco Shoppers

1. Get Yourself a Costco Shop Card

You don’t have to be a member to know how to get the most out of Costco. Using a Costco Shop Card will get you in the store where you can start saving right away. The Costco Shop Card is the retailer’s gift card that can be used on any purchase. Get yourself one of these, which range anywhere from $25 to $1,000, and you can start saving at Costco today! This is an excellent way to get a real taste of the Costco shopping experience before becoming a full-fledged member. If you ask us, this is one of the best Costco hacks most people don’t know about.

2. Shop the Kirkland Signature Brand

One of the not-so-well kept secrets of Costco shopping is buying the Kirkland Signature brand. This is Costco’s very own brand which offers most store products at some of the lowest prices. The quality of these products is the same as name-brand equivalents, yet they are a fraction of the price. From pantry staples to alcohol, you’ll find the Kirkland Signature brand down every aisle. You can shop smarter when you buy Kirkland products at Costco.

3. Buy in Bulk

What’s the most stereotypical way to get the most out of Costco? Buy more and shop less! One of the biggest advantages of shopping at Costco is the large selection of bulk items. Consider buying larger quantities of your pantry staples to get the best bang for your buck. Throwing a party? Get everything you need for making a large guest list happy for less. When you can, buy in bulk at Costco. Bulk items often contain less packaging, therefore decreasing your waste, too. Bulk buying is better for the planet, and your wallet!

4. Fill Your Tank Up

Not all of the best secrets of Costco shopping are for purchasing in the store. Sometimes keeping Costco deals in mind on your way into the store will help you save too. Filling up your tank at Costco gas stations will surely save you money. Costco shoppers usually save anywhere from $0.05 to $0.20 cents per gallon compared to other local gas stations. Costco has so much more than kitchen staples!

5. Earn Cash Back

If you’re shopping for a large family or happen to make hefty purchases at Costco, it might be a good time to upgrade your existing membership. For an additional $55 a year, upgrading your Gold Star Membership to an Executive Membership will automatically qualify you for up to 2% cash back on all your purchases. That will certainly add up quickly over the year, which is why this is limited to $750 in rewards annually. This has to be one of our favorite secrets of Costco shopping, not to mention shopping with Piggy will earn you extra cash back at Costco!

6. Utilize the Costco Pharmacy

Whether you have scripts to drop off or over the counter products on your list, including the Costco pharmacy in your next trip is one of the best Costco tips you could try out. Their nationwide full-service pharmacies have prices that compete with some of the major pharmacy chains. Speak to one of their in-house pharmacists during your next visit to see if you could benefit from filling your scripts while you shop. Some of their pharmacies are even open to non-members, but check your local store for details.

7. Buy Produce in Bulk (but only if you really plan on consuming it!)

One of the best Costco hacks is purchasing only what you are able to consume. Buying in bulk only works when you are able to reasonably consume it. One of the biggest wastes of money is buying produce in bulk that you end up throwing away anyway! Consider not throwing money in the bin and shop for your produce at Costco in reasonable quantities. While buying in bulk is an excellent way to save along the way, make sure you do so wisely.

8. Download the Costco App

One of the best hacks for Costco is keeping track of your grocery list on their app. This will help you stay organized and take advantage of the best deals on a weekly basis. Browsing the weekly store catalog before shopping at Costco will help you shop products that are in-season and score the lowest prices on everything you buy. Their two-day shipping will also help you out on orders with non-perishable items, too.
