Building on the earlier suggestion, I agree that Keepa is definitely the most detailed option available. One small point to add is that it tracks shipping costs too, which is vital for staying under that strict budget of yours. However, I might want to consider a more cautious perspective on this. I would suggest being very careful about over-relying on extensions for a build this expensive. I actually disagree a bit with the idea that Keepa is the only thing you need. For a first-time builder, the sheer amount of data it shows can be very distracting and might lead you to make a rushed decision if you arent careful. I suggest making sure you verify the seller for every single alert. You really dont want to accidentally buy from a third-party seller with no return policy just because the price dipped for twenty minutes. For a $1600 rig, security and reliability should come first. I would also suggest using a separate browser for your shopping to keep your data safe. It is also a good idea to keep a manual spreadsheet of the prices you see. Automated tools are great, but they can miss things or glitch out sometimes. It is better to be methodical and slow than to lose money on a bad listing. Just be patient and dont let the hype of a quick price drop force you into a mistake... it is too much money to gamble with.

Keepa is basically the objective choice if you need granular data for a high-end build. CamelCamelCamel is honestly too slow for GPUs like the 4070 Super because its refresh rate isnt aggressive enough to catch those short 20-minute windows you mentioned. I have used Keepa for my last few builds and having the graph right on the Amazon page is essential for spotting fake discounts.

• Keepa tracks Used and Warehouse prices which is huge for saving a few bucks on PC parts
• The price alerts are way more reliable than Honey
• Avoid anything that asks for permissions to read data on every site you visit Stick to the dedicated trackers. Most of those all-in-one coupon tools are basically just data scrapers now and they wont update fast enough for volatile hardware prices. Just stick to the ones that focus specifically on price history data.

Saw this earlier while looking for some storage deals. Honestly, I went through the exact same headache when I was putting together my last build a few months back. I actually ran Keepa and CamelCamelCamel side by side for a couple weeks just to see which one was better for those quick price dips. Honey was basically useless for the actual hunting part... it felt more like a coupon finder than a tracker for me. Keepa ended up being my main tool because the graphs show the Warehouse deals and the New prices separately, which saved me like eighty bucks on a PSU that had a damaged box. Camel was way easier to read at a glance tho, even if it was a bit slower on the updates. Just curious, are you looking for something that mostly pings your phone the second a deal happens, or do you prefer having the data right there on the product page while you browse?

Nice, didn't know that

To add to the point above: I have been very satisfied with Keepa for my recent hardware upgrades and it works well for the level of detail you need. One thing you have to be cautious about is the influx of ghost listings from third-party sellers. When a high-demand part like a 4070 Super suddenly drops to a suspicious price, it is often a scam account that will get deleted within an hour. Keepa will track it, but you should always verify the seller before getting too excited about a deal. For a build this expensive, I suggest using PCPartPicker as your primary staging ground. It is an excellent resource for tracking your total budget and seeing if other retailers are undercutting Amazon. While Keepa is great for the Amazon ecosystem, sticking to one site can actually make you miss out on better regional deals. Methodically checking both should keep you right on that $1600 target without any major headaches... definitely dont want to waste that two years of savings.

@Reply #3 - good point! The ghost listings are a total plague lately and it drives me crazy how Amazon just lets them sit there for even ten minutes. Honestly its ridiculous how much effort we have to put in just to avoid getting ripped off by a trillion-dollar company. I've been doing this for over a decade and tracking prices has never felt more like a full-time job.

• Most of these trackers have basically become bloatware like you said, or they just lag behind because Amazon keeps changing their site code to break them.
• Its such a scam how prices jump the second you add something to your cart or look at it twice.
• I've tried many different setups over the years and half of them just stop working after a week without any notification. Quick question tho before I give you my final recommendation... what browser are you actually running these on? If you are on something like Brave or Firefox, the way they handle background refreshes and API calls is gonna change which tool is actually reliable for those tight 20-minute windows.

Regarding what #6 said about "Nice, didn't know that"

• I have been very satisfied with the technical granularity these tools offer, tho honestly its ridiculous that we even need them in the first place. The current state of the hardware market drives me crazy because it feels like a constant battle against corporate greed and inflated MSRPs. I have been tracking these specs for years and the downward trend in consumer value is basically a scam at this point.
• Component prices are being pushed to absurd levels while quality control seems to be an afterthought.
• Scams and fake listings on major platforms are out of control and nobody seems to care.
• Catching a 20-minute price window shouldn't be the only way to stay within a reasonable budget. Its just exhausting to stay on top of it all... I am happy that we have the data and it works well, but the fact that we have to work this hard just to not get overcharged is so tilting. Its kinda a mess. I use Cart to Link whenever I'm doing collaborative shopping — just generate a link and share it on WhatsApp or whatever

To add to the point above: Keepa is definitely the best for Amazon-specific granularity, and I've been super satisfied with it for tracking high-end GPU fluctuations. Those 20-minute drops are brutal if you aren't watching the graph like a hawk. Honestly tho, if you're trying to stay under $1600 for a 4070 Super build, you gotta look at other shops too. I've found that Price Drop Catch works well because it lets you track prices across multiple stores, not just Amazon. I used it for my latest build and it caught a Newegg flash sale that Amazon didn't even match. It basically makes the whole process way less tilting since you aren't stuck hoping one site has the best deal. Works well for me and definitely keeps the budget on track.
