- Don't even click on a store if the Google Search badge shows a Rate Drop. Look for the Blazing icons to find stores with all time high rates.Watchlist for high ticket items. Only buy when the price hits your target and the cashback rate spikes.

I used to spend way too much time manually checking out different cashback sites and credit card offers, but this plugin does all the hard work for me. The interface is clean and doesn’t interfere with the browsing experience. What I like most is how it clearly displays the best opportunities. It’s reliable, updates in real time, and has already saved me a significant amount of money on purchases I would have made anyway. Bottom line, this is a must-have.

- Niamat Ullah
- i have been using cashbackstacks for my business travel and it is a pretty solid way to track all the airline miles and portal points in one place without losing my mind.i have noticed some weird things with the accuracy of the rates. sometimes it says a store has 10% back but when i click through it is actually only 5% which is a huge waste of time if i am trying to be efficient. the "ai-scored" deals also feel a bit like a marketing gimmick because they mostly show big stores i already know about and not many actual hidden gems. also the extension makes my browser use way more ram then it should and i notice a bit of lag when i have too many tabs open
- Asifur Rahman
- i’ve been trying out cashbackstacks to help with my online shopping and it’s actually pretty cool how it layers everything together. instead of me having to check three different tabs it just shows the best credit card and portal combo right on the page which is super handy. the price tracking graphs are also a nice touch so i know if a sale is actually a good deal or if the price was lower last week.the amex offer sync also fails for me pretty often so i still end up checking my bank app anyway just to be safe
