The Reason Costco Checks Receipts Isn't What You Think (And It Could Save You Money)

Many people think Costco checks receipts at the door to catch shoplifters, but that's not the whole story. In reality, this policy also makes sure you're charged correctly, which Costco emphasizes on its website. When you're leaving the store or warehouse, the staff at the doors take a quick look at your receipt to make sure everything adds up. A Costco executive once shared in an interview that checking receipts at the door is really about fixing mistakes quickly so they don't turn into bigger headaches.

The employee at the door is trained to look out for any mistakes, such as missing discounts or accidental double charges. This isn't about doubting you; it's a final check to protect your wallet. It's just another way the retail chain makes sure its customers get the best deal and trust stays strong. It is the same customer-centric ideology that makes Costco gas and Costco butter so cheap. It is also why you will save money if you buy a cut of lamb at Costco.

Costco's policy of checking receipts can save you money. A user on Thread.net narrated how a receipt checker identified a discrepancy in their receipt, where they had been charged for three items instead of two. This overcharge, amounting to more than $75, was quickly rectified with a refund. In another case, a checker noticed an error between the number of items in the cart and the number on the receipt — 12 items in the cart but only 11 listed. The checker discovered an unscanned case of La Croix at the bottom of the cart, which the cashier had not noticed.

In essence, scanning receipts means fewer issues for everyone. While Costco cuts down on later complaints and tracks inventory, it also ensures you only pay for what you actually bought. It's a win-win. However, it does not always turn out so well. For instance, another user on Thread.net shared how a receipt check at Costco revealed a cashier had missed scanning a box of ginger beer. This error meant she had to wait for a manager, pay for the missed item at the register, and then return to the exit, turning a simple check into a more time-consuming ordeal.

To ensure you don't spend too much time on the receipt checking line, organize your cart to match the layout of your receipt. Place larger items in a visible spot, and make sure items that spoil quickly, like baked goods or veggies, are easy to spot. This setup helps the exit staff quickly verify your purchases, especially the pricier ones. Also, check your receipt yourself as you approach the exit. Look for any obvious mistakes, like an incorrect number of items or bulk items that might have been split incorrectly. If something seems off, it's smarter to head to the customer service desk to clear it up before you try to leave.

Remember to view the receipt check as your last chance to snag any missed discounts. Sometimes, even with instant rebates, the rush at the checkout can cause them to be overlooked. Employees are good at catching these oversights to make sure you're charged the correct sale price. At the same time, know your rights; Costco does have the legal right to check your receipt as part of its membership agreement, but it cannot hold you back without a valid reason (usually shoplifting or other wrongdoings). If there's a mistake with your receipt, you can ask for a manager to fix it right there.
