After three hours, you’ve just emerged from the wormhole that is Costco.

What happened? Where am I?

You’re probably in the parking lot. Shielding your eyes from the blinding sun. Walking on tiptoes to your car so you can peer over your cartful of bulk paper towels, frozen chicken nuggets and animal crackers.

Your stomach probably feels full, too, because, well, free samples.

But you’re feeling proud because you saved money…

Wait, you did save some money… right?

It’s easy to get wrapped up in Costco’s branding. It’s a warehouse club, so it comes with the whole “save money on bulk” reputation.

But if you’re not careful, you could walk out of the wormhole spending way more money than you normally would. (Seriously… all those bulk snack options are so tempting.)

8 Secret Ways to Maximize Your Costco Savings

In order to avoid getting tangled in the wholesale web, we’ve compiled nine tips to help you stay on track and save more money.

1. Compare Prices

Before you even step into Costco, make sure you do some price-comparing.

Now, this doesn’t require you running around town.

We’ll get you started with the most obvious breakdown: comparing prices from warehouse clubs. Spoiler alert: Costco isn’t always the cheapest.

You can also take to the internet to compare prices or, if you’re already in the store, use an app like ShopSavvy.

And be sure to take into account the unit prices, because that modest two-pack of peanut butter might be a better deal than its six-pack counterpart. Plus, this will keep you from having to stash all those extra peanut butter jars under your bathroom sink.

2. Stop Deleting Your Emails

It turns out deleting your emails could be costing you serious money. Intrigued?

One of our secret weapons is called Paribus — a tool that gets you money back for your online purchases. It's free to sign up, and once you do, it will scan your email archives for any receipts. If it discovers you’ve purchased something from one of its monitored retailers, it will track the item’s price and help you get a refund anytime there’s a price drop.

Plus, if your guaranteed shipment shows up late, Paribus will help you get money back for what you paid for shipping.

3. Look for Membership Sign-Up Deals

If you haven’t already splurged on Costco’s $60 annual membership, look around the internet for any promotions or deals.

One of our favorite places to check is Groupon, the deals and coupons site. Earlier this year, it had a deal that would reward you in $155-worth of freebies. Unfortunately, that deal has since expired, but it’s worth poking around for similar offers.

Also, if you’re an avid Costco shopper, analyze the membership options and see which will most benefit you. If you opt for the $120 “Gold Star Executive” card, you can earn 2% rewards on qualifying purchases.

4. Use Ibotta for Cash Back

Ibotta is an app that gives you cold, hard cash back on your purchases from tons of retailers — including Costco.

Here’s what you do: Download the app, find cash-back offers you qualify for, take a photo of your receipt, scan barcodes if necessary and you’re done!

Once you redeem your first deal, you’ll snag a $10 welcome bonus.

At the time this article was written, available cash-back opportunities included:

  • $4 back on a 36-count pack of Scott toilet paper
  • $3 back on an 18-pack of Bud Light
  • $2 back on Aveeno baby products
  • 25 cents back on any kind of potatoes

New deals are constantly being shuffled in, so it’s a fun little cash-back game.

On a personal note, I started using Ibotta about five months ago and have earned nearly $100 back.

5. Understand Costco’s Price Codes

There’s a method to the pricing madness, and reporter Len Rapoport explained what he’s come to learn through the years in an article on Tough Nickel.

Here are some of Rapoport’s helpful hints:

  • Regular-priced items typically end in .99, .79, .49, etc. On the other hand, reduced prices end in .97. Unfortunately, Costco doesn’t share the original price with you, so it could be only a slight markdown. You can ask a sales associate to check on the original price for you to see if it’s a good deal.
  • An asterisk on a tag means the item won’t be restocked, so act now if you really want it.
  • Manager specials are marked by .88 or .00 endings. This means items were returned but are in fine condition. The box could be a little beat up, but who cares?

7. Pay With a Cash-Back Card

With so many cash-back credit cards on the market, it’s hard to know which one is going to offer you the best rewards.

But there’s a tool that’ll help you with this big decision: Even Financial offers an online marketplace to find the right card for you, based on your situation and needs.

Even reviews the information you provide it and considers cards from its partners.

You’ll enter your email, address, phone number and financial information, and Even will play matchmaker, connecting you with card issuers to see if you pre-qualify for the cards that are the best fit for you. (Pre-qualifying doesn’t commit you to a card or ding your credit score.)

8. Opt for The Store Brand

Be sure to keep an eye open for Kirkland-brand goods. That’s Costco’s store brand.

We hopped online to compare prices of Kirkland goods and non-Kirkland goods and found some hefty savings. For example, the Kirkland 36-pack of toilet paper is $25.99, whereas the Scott 36-pack of toilet paper is $33.49.

9. Fill Up Before Food Shopping

Grocery shopping on an empty stomach is one of the worst Penny-Hoarding offenses. Why? Well, you’re going to want to buy everything — from a $35 two-pound tin of cookies to a $37 48-pack of popcorn.

Instead, peruse the aisles and fill up on free samples. Or stop by the food court and grab a $1.50 hot-dog-and-soda combo.

Then do your shopping — with a list in hand!
