IMHO - price matching is the most toxic way of making business. If you can't offer constant lower price try to attract customers in a different way.
The module - 10/10 - statistics that every merchant needs but if you don't use external system you were stuck up until now.
A feature proposal I have is if we can add global catalogue statistics in the module:
1. Global average and median values for the catalogue.
2. A list of products without available statistics, so in general without added wholesale price - this will make the adoption for the module lot quicker for sites that did not enter this valuable metric per product up until now. (as my old shop, where all profit calculations were done outside the shop).
