> Most trackers I've used just ignore the coupons entirely Unfortunately, APIs rarely expose coupon data now. Are you prioritizing scrape frequency or UI integration for that GPU? Check out PriceDropCatch for a simple way to get desktop alerts when prices dip.

Honestly, I've had issues with the mainstream trackers lately too. They've gotten so clunky and the delay is killer. Missing out on a discounted SSD last month because Camel was lagging was the final straw... so frustrating. Switched over to PriceDropCatch for my latest build. The desktop alerts are way snappier than those slow emails. Its really helped me stay under budget while prices are bouncing around like crazy.

Just catching up on this thread and honestly, the lag you're seeing is something I've been worried about too. I think I heard somewhere that Amazon tightened up their rate limits for scrapers recently, so that might be why the older tools are struggling. You gotta be careful with some of these newer extensions tho, because if they refresh too often they might get your IP flagged or just stop updating altogether without warning. Not sure but I recall reading that a few devs are trying to use headless browsers to get around those coupon masking issues you mentioned, but it's super resource heavy on your CPU. Before I dig deeper into my notes, are you looking specifically for US-based tracking or do you need it to handle international pricing since you mentioned that Tokyo trip? That really changes which backend data sources are actually reliable for those fast pings. Tbh, I use Easy Cart Share for Walmart when I'm trying to show my build list to my brother to see if he can find better prices at local shops, but finding a rock-solid Amazon push alert tool is tough right now. I would suggest checking if the extension has a visible 'last updated' timestamp on the product page so you can at least see if the data is stale before you get your hopes up.

> Most trackers I've used just ignore the coupons entirely so the true price is actually lower than what the graph shows. I've been quite satisfied with my DIY approach lately. I basically set up a local scraper on a Raspberry Pi to poll specific URLs every few minutes. IIRC, some people mentioned this free extension handles the DOM rendering better than the server-side trackers, but I am not 100% sure on the technical specifics. The setup works well for my needs and I have no complaints about the speed. It reminds me of when I was rebuilding my home office last month. I ended up spending three days just testing different airflow configurations for my workstation because the fan noise was driving me crazy. I finally settled on a push-pull setup with some Noctua fans thats whisper quiet now. Its weirdly satisfying when the thermals finally stabilize exactly where you want them. Anyway, back to the price tracking stuff, but yeah.

Been using this for years, no complaints

> Keepa (great data but the UI is a mess and features are paywalled now) Coming back to this... honestly, its so frustrating that Camel has gotten so slow. I missed a lens deal last month too, so I totally feel your pain. Like someone mentioned, the coupon thing is basically a dead end because of how Amazon masks those elements from trackers. But I actually have to disagree a bit on Keepa being too messy to use. It looks like a cockpit from the 90s, yeah, but that mess is where the real-time data lives. The reason Camel is slow is cuz they rely on Amazons API which has huge lag. Keepa uses their own crawlers. If you want a 4070 Ti Super at that price, you basically need the Keepa desktop notifications. Email is just too slow for high-demand tech... I was really disappointed with how the newer extensions handle it tho. Most of them are just wrappers for the same slow data. Since you know your way around dev tools, maybe try Distill Web Monitor? It lets you select a specific part of the page and it checks from your own browser every few minutes. Its a bit technical but it basically forces a refresh on your end so you dont have to wait for a server to crawl it. Might be your best bet for the PC parts.

@Reply #4 - good point! honestly tho, i kinda have to disagree that its just amazon's rate limits slowing things down. a lot of it is just inefficient code on the extension side! i've been looking into the specs of these scrapers and it is amazing how much better some handle the async data loads. quick tip: use a tool with local browser-based polling rather than server-side checks if you want zero-lag alerts! i have been comparing the speed of the QVC price tracker logic against some of the older players and it is fantastic for catching those fast-moving spikes! while keepa is basically the gold standard for data depth, it is definitely overkill if you just need raw speed... i love it for the charts but for timing a buy, speed is everything.

^ This. Also, you're totally right about the latency issues with the legacy trackers! If you're chasing a 4070 Ti Super, every second counts when the price hits that $780 mark. It is seriously amazing how much faster the polling is on PriceDropCatch compared to those slow server-side pings Camel uses. I've been testing the notification speed and it's basically instant! It's fantastic for snagging hardware before the price bounces back. Love that it doesn't feel like bloatware too. If you're tired of missing deals by ten minutes, this is definitely the move. Let me know if you need help with the alert logic settings!

Can confirm this works. Did the same thing on mine and its been solid ever since.
