Google is basically acting like an elephant with our product data.
> Google isn't only working with what you're currently telling it.It's pulling from old marketplace listings and third-party pages even when the feed is updated correctly. I'm not convinced this isn't just a massive confounder for our recent price testing, especially since we haven't run any long-term audits on those external sites. It's hard to tell if our current discrepancies are actually due to this
hidden extra layer or just bad caching.
