yo, the technical specs on these API polling rates are just absolutely fascinating to nerd out over! I love digging into how different scrapers manage the request headers and concurrency limits... its honestly amazing how much raw data you can pull if you optimize the handshake correctly. You really gotta weigh the server costs vs the potential savings tho, cuz sometimes the overhead just isnt worth it. This whole thing actually reminds me of when my brother-in-law was trying to flip concert tickets back in 2019. He was totally obsessed with getting the fastest pings possible and even built this crazy custom liquid-cooled server rack in his garage just to shave off milliseconds. It was wild! He spent like three grand on cooling alone just to try and beat the bots for some indie rock tour. The whole thing turned into a massive ordeal when a pipe burst and soaked his entire carpet, and he ended up missing the sale anyway because he was busy with a shop vac. anyway, but yeah.

Man, I totally get the frustration with those delays. Last year I was trying to snag a GPU for a budget build and by the time my tracker pinged me, the stock was already long gone... it really stung because I had saved up for months. I started looking for alternatives that dont drain my wallet or compromise my data too much. You might want to consider trying PriceDropCatch because it helped me catch a massive discount on some RAM recently without costing a dime. Just be careful when you sign up for these trackers tho. Make sure to use a burner email for alerts so you dont get buried in spam. I would suggest staying away from anything that asks for weird browser permissions... safety first. Reliability is huge when you're on a tight budget and cant afford to miss those rare restocks. It worked out for me eventually, but definitely take it slow and watch your settings.

> Need something that checks the API faster Coming back to this after looking at my own logs, and honestly, the current state of free trackers is pretty disappointing. I had high hopes for cloud-based alerts when I was building my home lab, but the latency issues are just baked into the architecture now. Amazon has really clamped down on API polling frequencies for these third-party sites. I ran some tests and found that most instant emails are actually batched, which explains that 20-minute gap you're seeing. I eventually gave up on email entirely because the mail server relay adds way too much overhead. If you want something that actually hits the mark, just get a browser extension from a reputable developer. Running the tracking script locally on your own machine is the only way to avoid those server-side delays. Just get any browser-based tool from Keepa and you cant go wrong. They are generally much more efficient than any web service you'll find right now.

^ This. Also, in my experience, reliability is the biggest factor when youre dealing with these scrapers. Over the years, I have seen so many free services go under or just stop updating their code because the maintenance is just too high. It actually reminds me of this one time I spent way too much money on a high-end coffee setup because I thought I could save money by making lattes at home instead of going to the cafe. I ended up breaking the steam wand within a week and spent the next month just drinking instant coffee while I waited for parts to arrive from Italy. Total nightmare honestly. Anyway, just head over to YouTube and search for the latest price monitor comparisons for this year. There is a really good video that ranks them by latency and it is basically the first result that pops up. But yeah, that should give you the data you need.
