Honestly, you're not wasting your time, but you gotta manage your expectations with Walmart specifically. In my experience, Walmart is super stingy with site-wide coupon codes compared to other retailers. Over the years, I have tried just about every extension out there, and most of them just cycle through expired codes that never work. Honey is fine for general stuff, but honestly, it rarely pulls a win at Walmart. If you really want to save, stop relying on extensions and check the official Walmart rollback page instead. It is way more reliable than those browser plug-ins. Just keep in mind that those extensions collect a ton of your data, so be careful what you install just to save a few bucks on boxes. Good luck with the move, moving is a total pain!
