10 Common Mistakes When Using Promo Codes (And How to Avoid Them)
Promo codes can help you score significant savings on your online purchases — but only if you use them correctly. Many shoppers unknowingly miss out on discounts or even overpay due to small errors during checkout. In this article, we cover the 10 most common promo code mistakes and how to avoid them so you can make every deal count.
1. Using Expired Codes
One of the most frequent mistakes is trying to apply a code that has already expired. Always double-check the validity date on the site where you found the code.
2. Not Meeting Minimum Spend Requirements
Some codes require a minimum purchase amount. If your cart total doesn’t meet the threshold, the code won’t apply. Always read the terms before trying the code.
3. Typos in the Promo Code
Promo codes are often case-sensitive and must be entered exactly as provided. A simple typo can invalidate the discount. Always copy and paste instead of typing manually.
4. Not Checking Item Exclusions
Some brands exclude certain products or categories from promotions. Make sure the items in your cart are eligible for the promo.
5. Forgetting to Apply the Code
This happens more often than you think. Shoppers reach checkout and pay full price without realizing they forgot to paste the code. Make using a promo code a final step in your shopping process.
6. Overlooking Stackable Options
Some retailers allow you to stack multiple discounts — like a coupon + free shipping + cashback. Check if your store supports combining offers and maximize your savings.
7. Using Incompatible Browser Extensions
Extensions like Honey or Capital One Shopping are helpful, but occasionally they may interfere with your code or checkout. If your code doesn’t work, try again in an incognito window or disable the extension temporarily.
8. Ignoring Cashback Opportunities
Many people use a coupon and skip cashback — missing out on extra savings. Platforms like Rakuten or Shoop often work even when you use a promo code. Use both!
9. Not Reading the Fine Print
Promo codes may be valid only for first-time buyers, certain countries, or specific payment methods. Read the fine print to avoid surprises.
10. Relying on One Source for Codes
If you only use one site or app, you may miss out on better codes elsewhere. Check multiple sources like OneClickPromo.com, browser extensions, and email newsletters for the best deal.
