Totally agree with the previous reply, extensions are basically just privacy nightmares waiting to happen. If you want email alerts without that mess, you should check out BrickSeek. It is pretty much the go-to for tracking those price swings without needing to install anything shady. I have used it for years to keep tabs on inventory and price drops. It handles Walmart pretty well compared to the other sites I have tried. Just search for your set and set up the notification settings. Ngl, it is not always perfect and sometimes the data lags by a few hours, but it is way better than refreshing the page manually all day long. It is a solid way to make sure you dont overpay for a gift, especially with Lego sets.

Honestly, tracking Lego prices is a total headache because they fluctuate constantly. Over the years, I've tried many different tools, but honestly, browser extensions are usually just data scrapers, so avoiding them is smart. In my experience, the best way to get actual email alerts without installing weird software is to use a dedicated service. Here is how I manage it:

• Sign up for a reliable Walmart price tracker that sends direct emails.
• Make sure you set your target price slightly above the historical low so you get notified before it sells out.
• Keep an eye on the third-party sellers too, but stick to items shipped and sold by Walmart to be safe. It works way better than checking manually every day. Good luck with the birthday gift, hope he loves it.
