Before checking out, I follow a simple verification process to avoid wasting time on dead coupons. First, I look for recent user comments or timestamps showing when the code was last confirmed to work. Then I test it in an incognito window and try switching currencies or regions, since some discounts are geo-locked. I also compare the price with and without logging in, as some brands restrict public codes. As a final step, I cross-check on a reliable tracker like https://savemycent.com/ to filter out obviously expired coupons.
Good list. I’d add: avoid codes that require sketchy browser extensions. Real coupons usually apply directly at checkout without asking for “permissions.”
