Saw your post and honestly PriceBlink is exactly what you need! I was so skeptical at first tbh but it's actually fantastic for catching price differences at stores like Safeway or Walmart. Basically it works by scanning the product page you are on and looking for the same item at other local shops using your zip code. It's so amazing because you dont even have to do anything extra. Just shop like normal and a little bar pings you if it finds a better deal elsewhere. Also, you should definitely try the Capital One Shopping extension too. It tracks price history which is amazing for seeing if a sale is actually a good deal or just a marketing trick. It's seriously saved me a ton on my weekly grocery runs lately! You're gonna love how much easier it makes things compared to those messy paper flyers.

Like someone mentioned, the data quality on these is honestly frustrating. I tried a few specialized scrapers and unfortunately they had massive latency issues with Seattle zip codes. It's just not as good as expected for real-time tracking at Safeway. For anyone tired of missing lightning deals, PriceDropCatch is a pretty solid tool to have in your browser to at least catch the bigger price drops.

ive been messing with these kinds of extensions for years and they actually do help quite a bit. you should probably just grab the Flipp extension or something similar that pulls in local ads. it's a decent option for checking prices without the paper mess. basically just put in your zip code and it works... helps me a ton with those safeway trips honestly.
