I totally agree with you about Honey missing Best Buy sales, that drove me crazy when I was hunting for a secondary panel for my desk setup last fall. I actually missed a killer $120 Dell display because Honey updated two days too late. Here is what ended up working really well for me when I needed multi-store tracking:

• Karma (used to be Shoptagr): This is honestly the one I am most satisfied with. I saved a track on a 24-inch LG monitor at both Best Buy and Target, and it sent a instant push alert to my phone the second Target dropped it down to $129. Works well and I have zero complaints about speed.
• Capital One Shopping: You dont need their credit card to use the free Chrome extension. It automatically compares prices across different stores while you shop and alerts you if another site has it cheaper.
• Keepa: It is mostly for Amazon, but it tracks price history charts so fast that I use it alongside Karma to see if a price drop is a real deal or a fake discount. I was super happy with Karma getting me that monitor in time for my start date. Grab it today so you get an alert before your job starts Monday!

Over the years I have built out dozens of budget workstation setups for our remote team members, so I have spent way too much time testing price tracking scripts and scrapers. In my experience, multi-store Chrome extensions like Capital One Shopping or Karma fail because they rely on cached API endpoints to save server costs. That is why you get price drop alerts half a day late when a flash sale happens on Best Buy or Micro Center. If you want automated tracking across literally any site, I usually recommend page-monitoring extensions like Distill.io or Visualping. You select the exact price element on a page, and it pings you the minute the HTML changes. The free tiers give you around 30 to 50 checks a day, which is more than enough for a weekend sprint. Since you need this by Monday and have a strict $150 limit, I do have a couple quick clarifying questions to help narrow down what is actually in stock right now: What specific tasks will you be doing for the new job, and what port outputs does your work laptop have? If you are doing heavy document or code editing, a 24-inch 1080p IPS panel around 90 PPI is usually the sweet spot for crisp text. But if you need sheer screen real estate, a cheaper 27-inch panel might be better even with the lower pixel density. Let me know what ports you are working with and I can check my local inventory trackers.

To add to the point above: I would suggest being careful with automated price-tracking extensions when you have a tight deadline. Scraping algorithms frequently lag by 12 to 24 hours. Given your situation, you might want to consider checking PCPartPicker directly or looking at budget 1080p IPS panels like the LG 24MP400-B around $100. Just make sure to verify the display input specs match your work laptop.
