Distill Web Monitor is the sleeper tool you want. I used it to snag my rack components last year when everything else was lagging. It runs locally so you arent waiting on a server to crawl the page.

• Set the check interval to 5 seconds.
• Select only the price element to avoid false pings. Its more work than Keepa, but the local refresh rate is unbeatable for limited stock.

Jumping in here because I have dealt with this exact frustration over the years while building server racks. Quick question tho... are you usually at your desk when these drops happen or do you need the alerts to hit your phone while you're out? It makes a huge difference in which route you should take for the fastest pings. In my experience, the Keepa premium sub is actually worth it for a one-month sprint like yours. I know the UI is a total mess and feels super cluttered, but the real value is the frequency of the data refreshes. Most free trackers scrape every few hours, but high-demand items like a 4090 or those Samsung monitors have price swings that only last minutes. The premium pings are basically instantaneous because they use the API rather than standard web scraping. Since you're dropping 4.5k, the small fee for one month of access is probably the most cost-effective move to ensure you dont miss those lightning deals.

I totally agree with Jason about Keepa premium being worth it for a short sprint like this, but honestly, you gotta be careful not to get overwhelmed. Camel is basically a toy compared to the data Keepa pulls. The reason Keepa is better for high-end stuff like a 4090 is because it tracks the Buy Box specifically. Camel often misses when a price drops but the main seller changes. But seriously, make sure to ignore the Statistics tab at first or your head will spin. I would suggest just focusing on the pink and blue lines on the main graph. Also, watch out for those third-party sellers with zero reviews... if a 4090 drops to 1200 bucks out of nowhere, its probably a scam and Keepa will ping you for it regardless. Stick to Sold by Amazon alerts to stay safe. TL;DR: Keepa is superior because it tracks Buy Box and Warehouse stock in real-time, just dont let the cluttered UI distract you from the main price graph. Btw I use Share Product for my holiday shopping lists, definitely worth a look if you're struggling with the Amazon app.

Building on the earlier suggestion, we've already touched on local monitoring and the mobile versus desktop alert situation. It really comes down to how much stress you can handle! This reminds me of my 3090 Ti build where I used PriceDropCatch and obsessed over VRM specs. One night I got so hyped for a price drop that I knocked over my soldering iron and nearly torched my rug! Total disaster but such a rush!

@Reply #6 - good point! Honestly, just biting the bullet on Keepa for a month is the way to go because speed is the only thing that matters for a 4090. I have tried many tools over the years and the free ones usually lag too much when you are in a three-week crunch. Since you are trying to save for a chair, definitely check out the warehouse deals for that monitor. People return those massive screens constantly. In my experience, you can often find like new ones for hundreds less just because the box was dinged. I usually set up an Amazon wishlist creator to keep my specific parts list clean so I can check for those open-box deals manually every morning. It is a bit more work but the savings are way better for the long-term than just waiting for a price drop on brand new stock. Keeping that 4500 budget tight is tough with a 4090 but it is doable if you are aggressive.

Did this last week, worked perfectly
