Costco Price Adjustments Made Easy: My Review of the CostPal App

CostPal alerts shoppers when Costco purchases drop in price, making it easy to claim refunds through Costco's price adjustment program.

Costco can save you a lot of money—as long as you don't leave with a kayak, a giant teddy bear, and a 72-pound wheel of Parmesan cheese you never intended to buy.

What many Costco shoppers don't realize, though, is that Costco has a 30-day price adjustment policy. If something you buy goes on sale within 30 days, Costco will refund the difference.

Sounds great, right? But here’s the catch.

You have to request the refund, and it’s up to you to know if an item went on sale. Unsurprisingly, Costco isn't sending out reminders that it owes you money.

If you're thinking you'll have to wander Costco every week checking price tags, don't worry. There's a much easier way.

For the past year, I've been using an app that does the heavy lifting for me: CostPal.

Note: CostPal didn't sponsor this post, and I'm not affiliated with them in any way. I'm simply sharing an app I've personally used and found helpful.

WHAT IS COSTPAL?

CostPal (formerly Costco Companion) is a third-party app that monitors your Costco purchases and alerts you when an item drops in price during Costco's 30-day adjustment window.

The notification will list:

• Item SKU and description

• Costco branch where the item was purchased

• Eligible price adjustment dollar amount

• Deadline to request the price adjustment

CostPal tracks both warehouse and online purchases, so you don't have to remember where you bought something.

HOW COSTCO PRICE ADJUSTMENTS WORK

You can read the full price adjustment policy, which Costco refers to as price matching, listed on its Customer Service page.

But here are the main things to be aware of.

1. 30-day window: Price adjustments must be requested within 30 days of purchase. So pay attention to the deadline listed in the price adjustment notification!

   
   

2. Sale must still be active: In addition to the 30-day window, the sale must still be active at the time of your refund request. Sales typically last a while, but don’t wait too long to request your price adjustment.

   
   

3. Go back to the same Costco center: I learned this one the hard way. Price adjustments must be processed at the same Costco where you made the purchase. Save yourself the extra drive and head back to the original warehouse.

   
   

4. Don’t forget your debit or credit card: Costco will credit any adjustment back to the original form of payment. Store credit isn’t an option, so if you paid with debit or credit, don’t forget your card.

HOW TO USE COSTPAL

If you can take a photo of a receipt, you can use CostPal.

STEP 1: Upload a receipt to the app. Digital receipts are available in your online Costco account, but I find it easiest to take a photo using the in-app camera.

STEP 2: Confirm the Costco branch and date of purchase.

STEP 3: Once CostPal notifies you of a price drop, return to the Costco branch where the purchase was made and request your refund at the price adjustment counter.

Pay attention to the how many days left you have to claim a price adjustment.

The price adjustment counter is different from the counter that processes returns. It’s usually a single standalone register found at the end of the checkout stands towards the exit.

Have either your membership card or your receipt ready, and simply let the employee know which item(s) you’re requesting a price adjustment on. I like highlighting the item on the receipt to make things easier for everyone.

IS COSTPAL WORTH PAYING FOR?

The CostPal app itself is free; however, you must purchase credits. Each dollar in savings the app finds uses one credit. For example, a $6 price drop will use 6 credits.

In practice, I've found the credits cost far less than the refunds the app uncovers. And credits sometimes go on sale during major holidays.

You get 5 free credits to start, after which additional credits can be purchased through the app.  And even at the smallest credit package, you're still keeping roughly 80% of the savings CostPal finds for you.

Heavy Costco users can even opt for a subscription plan starting at $2.99 a month.

I recommend starting with a pay-as-you-go plan until you figure out how much you can potentially save. Points never expire, so you won't lose anything.

FAQ

Does Costco Automatically Refund Price Drops?

If it only were that easy! You must request the adjustment yourself.

Can CostPal Request the Refund for Me?

No. CostPal only alerts you when a price drop occurs.

Can I Get a Costco Price Adjustment Online?

For in-warehouse purchases, you must return to the same warehouse. For online purchases, Costco has a separate online adjustment process. Go to the Customer Service page and look for Price Match to submit a request.

SO, IS COSTPAL WORTH IT?

CostPal isn't going to make you rich. In our first year, our biggest refund was $9 on two boxes of crackers. We were thrilled to get it even though it wasn’t life-changing.

But that's kind of the point.

Financial independence usually isn't built on one big win. It's built on dozens of small systems that quietly save money in the background while you go about your life.

That's what I like most about CostPal. I don't have to clip coupons, hunt through weekly ads, or change my shopping habits. I upload a receipt, let the app do its thing, and occasionally collect money owed to me during my usual Costco runs.

It's not life-changing money. But if someone wants to hand me a few extra dollars for almost no effort, I'm not going to argue.
