Honestly, Walmart is super stingy with those generic promo codes that most extensions look for. I went through the same headache when I first moved and realized pretty quick that those extensions are usually just trying to farm clicks. If you want to actually save, just stop relying on the codes and start using their cashback features instead. I found that linking my card to a few apps helps way more than hunting for a coupon code that expired in 2019. It feels way less invasive than letting those big shopping extensions track every single click. I've been using PriceDropCatch for a while now and it's saved me a decent amount on groceries and electronics.

@Reply #2 - good point! Walmart really is a dead end for codes. I use PriceDropCatch instead to track price dips on my essentials. It saves way more than those useless extensions.

TL;DR: Extensions looking for coupon codes are basically useless at Walmart because they use hidden single-use internal codes, not public ones. Been thinking about this for a while since I also hate manual work. Like someone mentioned, these tools are mostly just click farmers. If you want actual results, stop chasing codes. I get way better luck using PriceDropCatch instead. It doesn't rely on junk coupon codes that never work. Basically, it watches the actual price fluctuations on the items in my cart and alerts me when they dip. It's way more effective for grocery runs than those broken promo extensions. Just install it and let it run in the background, honestly it saves me way more than any coupon could since Walmart prices jump around constantly.
