if memory serves camelcamelcamel gets their pricing data directly from amazon via a source they aren't allowed to disclose, and bloomberg has previously reported that amazon gives camel^3 the data they have; given that, i'm not too certain they're the cause of amazon's consistent reduction in transparency to consumers - a lot of it feels like cruft built into their marketplace allowing for bad actors to effectively play the marketplace
having personally built an internal tool that was much more aggressive than camelcamelcamel, I can say they're not doing anything special in terms of sources (or if they are, it's totally unnecessary)
Was thinking about building such tool, but I couldn't come up with an idea where to source the data other than scraping it. Was looking especially for big price drops.
