TL;DR: Distill Web Monitor beats Keepa for raw speed. Distill runs locally on your PC, meaning you set the check frequency as low as you want. Pros: near-instant alerts. Cons: your computer must stay awake. Another option is a custom Python script using the Amazon PA-API. It is technical to set up but has the lowest latency possible. Ngl, it is way more reliable than waiting for third-party server queues. Just shout if you need help with the specs!

Did this last week, worked perfectly

Man, I feel that pain with the 4070! That card is amazing but the market is so competitive right now. The technical reality is that legacy trackers are balancing millions of users, so their notification queues are totally bogged down. They use a tiered scraping system where popular items get checked often, but the API overhead still creates that 30-minute lag you're seeing. I switched over to using Glass It recently and the response time is incredible! Honestly, it changed the game for me. It basically polls at a much higher frequency than the big scrapers.

• It utilizes a way more direct price-tracking algorithm that doesnt get stuck in standard cache loops.
• The mobile alerts are basically instantaneous because they use a leaner notification bridge.
• You get a visual verification which is fantastic for confirming lightning deals. For a high-stakes build like yours, you need that sub-minute response time. Youre gonna get that card next time tho! It's gonna look fantastic when it's done!

That Python script suggestion is honestly the gold standard if you have the patience for it. I totally agree that moving away from the big bloated services is the only way to beat the crowds now. But seriously, you might want to consider being cautious with how fast you ping their servers. If you go too aggressive, Amazon will just hit you with a captcha or a soft ban, and then you will definitely miss the next 4070 drop. I would suggest keeping a few things in mind for reliability:

• Put your script on a cheap cloud server so it is not dependent on your home internet staying up.
• Use Discord webhooks for the alerts because they seem way more stable than standard phone apps.
• Double check the product ID is exactly right or you will be tracking the wrong SKU for days. I actually use Cart to Link when I am building lists for friends so they can see everything I have grabbed in one go without the mess. It makes things way easier than sending a bunch of separate screenshots or links. Just watch those refresh rates tho... it is a fine line between being fast and getting your IP flagged.
