I was hunting for a Samsung 990 PRO 2TB NVMe SSD a few weeks back and really didnt want to sign up for another service that would just spam my inbox. I basically spent a whole afternoon looking at how these things scrape data. Most sites actually let you view the full history graphs without a login if you just paste the link. I've been using this method for a while and honestly, I'm pretty happy with it:

• i just bookmark the specific price graph page instead of setting an email alert
• check it once a day when i open my browser
• compare the current price to the historical lowest mark on the chart It works well because it relies on the site's public data rather than a user profile. Since i'm usually on my pc anyway, it's not a big deal to just click a bookmark. No account, no hassle, and i still get the technical breakdown of the price trends... pretty satisfied with that setup tbh.
