Receiving notifications of dramatically incorrect price change on Amazon #313

Open javaun opened 5 years ago

I'm just filing this to hold it and will ask others to try to reproduce. Let's hold this for now. While Price tracker is on hold, we are still doing Fathom work. I want to know if this is a recognition problem (fathom training), or if it's something else.

I'm getting notifications that this Lego set drops to $15.00, but when i visit the page it's $249. https://www.amazon.com/LEGO-NINJAGO-MOVIE-Docks-Building/dp/B07BKLR4D8/

The Price Tracker doorhanger also has the correct price $249 (But that's after I visit the Amazon page, so maybe it's re-checking.

I'll ask other internal users to see if they can reproduce, and that may tell us that it's just my machine

Thanks javaun for filing this issue.

As discussed internally,

Price Tracker is currently never using Fathom's extraction results as of this PR: https://github.com/mozilla/price-tracker/pull/275 , because my original Fathom extraction code set a minimum score threshold of 4, and Erik's new ruleset scored elements on a scale of [0, 1].

After trying this page out myself, it is using CSS selectors for the product extraction.

As far as where the $15.00 is coming from, I'd have to do more digging.
