The Costco price system

The Costco price system

At Costco, numbers tell a story; they reveal information about how much you can save on an item. However, only a few people know how to read the price code.

Here’s what each Costco price code means:

  • When the product has a price tag that ends with .97, it indicates the product is currently on clearance sale (clearance items save you the most money, so look out for those)
  • When it ends with .00 or .88, it’s on a manager’s special discount
  • When it ends with or has an asterisk attached to it, that means Costco will not be restocking that item
  • If it has none of these price codes, that implies that’s the products regular price

Understanding this system puts you one step ahead of other shoppers and helps you save on your future shopping trips to Costco.

Buying in bulk means extra ways to save

Shop online

Shop online

Shopping online, either on the Costco app or website, is a great way to save money.

Items sold on Costco’s website (and mobile app) are far cheaper than what you can find in-store. Many products are $10, $20, even $30 less online than those sold in the stores. Shopping online saves you the time you’d spend going to the store and also helps you keep extra cash in your wallet.
Shop with friends

Shop with friends

At Costco the more you buy, the more you can save.

However, if you don't have enough space to store extra items or don’t want to buy them in bulk, you can plan to buy the bulk items with a couple of friends. This way you can all still save money without having an overload of items.
Go for in-house brands

Go for in-house brands

In-house brands help retailers, like Costco, save a lot of money on marketing premiums.

Kirkland is Costco’s in-house brand and is a lot cheaper than their big-name counterparts. Items such as toilet paper, medications, coffee pods, trash bags, men’s, women’s and kids’ clothing, wine, peanut butter, and even dog food are amongst those sold under the Kirkland brand name.

Get access to the Costco coupon book

Though the wholesaler is pretty restricted in dishing out Costco coupon codes via email, they make up for it with their coupon book.

The Costco coupon book is a treasure trove of very decent deals showing you the very best offers of the current month.

In it, you can find big brand name products, including Apple, for as much as 40% off. Other offers include:

  • Tires at $70 off
  • Protein powder
  • Cookies and other canned foods at $11 off
  • Mattress toppers at $20 - $35 off
  • Kitchen-wares at $8 off

If you want to save shopping with Costco, the coupon book should be your closest companion.

Take advantage of the price protection guarantee

Extensive guarantees buffer every purchase at Costco, and this makes shopping with them completely worry-free.

If you buy an item at Costco and find out a few days later that it has dropped in price, you can return it to Costco and repurchase it at the lower price or get the price difference.

This price protection policy allows a 30-day period for returns, and there’s also a 90-day return policy for any item that doesn't satisfy your needs.
