To add to the point above: I actually disagree that scraping Amazon is worth the hassle. Amazon dynamic pricing algorithms are too volatile anyway.

• Look at Tamron or Sigma, you cant go wrong with their budget zoom lenses for Sony.
• Check used pricing datasets on MPB instead.
• Prices there are fixed and usually beat Amazon's best sales anyway.

> Every single price tracker I find online keeps demanding my email or making me link my Google account just to set up a basic alert. Unfortunately, the state of public price tracking has really gone downhill. Keepa has heavily restricted their historical data access for guest users, and CamelCamelCamel is not as good as expected anymore since they started pushing account walls. They basically force data collection on us now. If you want a zero-account setup, your best option is running a local monitor. You can install a browser extension like Distill Web Monitor and configure the tracker to run locally on your device rather than using their cloud service. This saves all the data in your browser local storage and triggers a desktop notification when the price drops, requiring zero registration. Another method is hosting a basic Python script. You can scrape the Amazon product page using a library like BeautifulSoup combined with a free headers wrapper to bypass the bot detection. It only takes about 20 lines of code to check the price and log it to a local text file. It is disappointing we have to resort to workarounds just to track a simple Sony lens, but it beats giving away your personal inbox.

^ This. Also, in my experience, relying on local extensions or DIY scrapers for a time sensitive purchase is a huge mistake. Over the years I have seen too many people miss deals because of a few common traps:

• Local browser monitors fail silently when Amazon changes its DOM layout or soft bans your home IP
• If your computer goes to sleep during a flash sale, you miss the window completely
• Clearing your browser cache or cookies wipes your tracking settings instantly If you are on a tight deadline for your trip, dont trust a setup that relies on your PC staying awake 24/7. I set a target price in Price Drop Catch and just forgot about it, got the alert like 3 weeks later and saved $60.

I ran into this exact issue last year when tracking a Fuji lens. Since I refused to create another account, I ended up setting up a local scraping script using Python. But honestly, Amazon is incredibly aggressive with their anti-scraping measures now. You might want to consider using a local browser extension like Distill Web Monitor instead. Be careful though, because if you run it locally without an account, it only checks the price when your computer is actually awake. If you go this route, make sure to set the check intervals to at least 3-4 hours, otherwise Amazon will block your IP address thinking you are a bot. It is a bit of a workaround but it keeps your data private.
