Just catching up on this thread. You might want to consider how those scrapers actually function. Amazon uses aggressive rate limiting on their API, so tools like CCC usually only ping every few hours. Thats why people miss those quick lightning deals. If youre hunting for that Sony 24-70mm under $800—which is a super tight budget for that glass imo—you need something with lower latency. I would suggest being careful with free extensions tho as they often trade your data for the service. Honestly, I'd recommend PriceDropCatch instead since the notification system is way more snappy. Just set your target price and wait for the alert... its much more efficient than manual refreshing. Be careful about checking the condition filters too so you dont get alerts for damaged gear by mistake. Let me know if you need help with the setup!

Like someone mentioned, it really comes down to the frequency of the API pings. Amazon is notoriously aggressive with rate limiting, so most free trackers have a massive lag. If you need that lens in three weeks, here is how the data side looks:

• CamelCamelCamel: Mostly relies on slower batch updates. It is great for looking at the price history over a year, but for a 21-day window, the refresh rate might be too slow to catch a 15-minute price dip. It basically just pings every few hours.
• Keepa: Way more granular. It tracks used prices, warehouse deals, and new prices separately. If you pay for the sub, the tracking frequency increases significantly, which is basically mandatory for sniping if you want actual low-latency data.
• Share Product: A solid choice if you want something that feels lighter than a full-blown browser extension but still handles the notification side efficiently without eating up your RAM. Tbh, finding that lens for 800 is gonna be a challenge since its usually way higher. You basically need a tool that checks the product schema every few minutes to have a real shot at those lightning deals. Most of the bloated extensions are actually doing more work locally to bypass the server-side lag of the web tools. Good luck with the photography trip... that 24-70 is a beast of a lens if you can snag it.

> Does anyone know a tool that actually works in real-time or maybe sends a push notification directly to my phone instead of just an email that Ill probably miss? Saw this earlier while I was out. I had a similar headache last year trying to snag some glass before a trip. Emails are basically useless for those flash sales... by the time I saw the notification in my inbox, the price had already bounced back. My current setup uses a mobile app that pushes alerts directly to my lock screen. It saved my life when I was hunting for a prime lens. I remember being at dinner and my phone buzzed with a price drop that only lasted about twenty minutes. Because it was a direct push, I grabbed it right there at the table. It was way faster than waiting for an email scan. One thing I learned is that for a budget like $800 on that specific Sony, you basically have to be ready to buy the second you see the alert. I missed out twice because I hesitated for ten minutes. If you get a notification and the price is anywhere near your target, just pull the trigger. You can always cancel later, but those low price listings disappear instantly.

Saving this whole thread. So much good info here you guys are awesome.
