[feature] Trig notification when price changes by pre-defined % difference or goes beyond a predefined value

Open cellulosa opened this issue 1 year ago • 3 comments

(I apologise if this functionality already exists, as I was unable to locate it.)

It would be highly beneficial to have the capability to track not just any alteration, but specifically when a price shift exceeds a certain percentage or when it drops below a particular value, similar to the features offered by CamelCamelCamel.

This is not only valuable because it enables alerts only when a product falls within my budget range, but it also serves to minimize receiving unnecessary notifications. For instance, I'm tracking a software's price page that often alters by approximately +-$0.01, which results in frequent, irrelevant alerts.

Thanks

yeah the whole price thing needs to be re-evaluated, it should be much easier to follow this information - includes https://github.com/dgtlmoon/changedetection.io/pull/2041

yeah be cool to position ourselves as a self-hosted CamelCamelCamel alternative.

Amazon doesnt appear to have any embedded machine-readable (LD JSON etc) price/stock information, so I suspect that CamelCamelCamel are using the amazon API to get the prices and so have very specific amazon code
