Hey, tried your thing, it&#x27;s a good start! The site itself is laid out very well, and the searches we&#x27;re fast as hell. It looks useful, I hope you keep working on it.<p>As a test I searched for &quot;switch&quot;, I was being intentionally vague, but I meant &quot;Nintendo&#x27;s Switch Console&quot;. The switch query brings up a bunch of switch related accessories and games, which was ballpark what I was looking for, but not quite.<p>I tried &quot;Nintendo Switch&quot; next, which brought up a bunch of different versions of the Switch, but Walmart kinda overwhelmed other marketplaces. Although two did pop up from Best Buy in the second page for me.<p>I tried &quot;Switch Console&quot; next, and it was 100% Walmart listings for at least three pages.<p>The sites still useful as it, it just takes a little digging to get what ya want. Search is hard as hell, it&#x27;s understandable. As this evolves, it would be nice if you tried to normalize products across different stores and showed them in aggregate, so if I search &quot;Nintendo Switch&quot; I&#x27;ll get results from every store that carries the &quot;Nintendo Switch OLED, White Model&quot; together. It&#x27;d be super easy to track the cheapest price for the specific thing I&#x27;m looking for over time that way.<p>Did you see the post about the release of CozoDB 0.6 a little while back? I&#x27;m not affiliated with the project, but building product ontologies was one of the examples he gave. Maybe check it out? <a href="https:&#x2F;&#x2F;docs.cozodb.org&#x2F;en&#x2F;latest&#x2F;releases&#x2F;v0.6.html" rel="nofollow">https:&#x2F;&#x2F;docs.cozodb.org&#x2F;en&#x2F;latest&#x2F;releases&#x2F;v0.6.html</a>

I&#x27;m working on Costbot, a price tracking tool designed to help online shoppers save time and money by monitoring price histories and alerting them when their favorite products hit their target prices. The side-project recently become done &quot;enough&quot; to be shared in small fashion, and wanted to ask for feedback&#x2F;thoughts etc. on here.<p>I&#x27;m a staff software engineer by trade, but love working on side projects in my (relatively rare) spare moments. This has been a fun project, involving some new things I hadn&#x27;t worked on before (extended parsing &#x2F; crawling, scraping, headless browsers etc.). Hoping to put together a write-up on the tech soon.
