We do use (as inputs) problems folks report with replacements (which include “too expensive” as an option), so theoretically this is covered, but I do think that we will be looking at the initial ranking and boosting as it seems this is a consistent problem. As I noted elsewhere, we will be looking at better collecting preferences from customers as “the majority of customers” approaches don’t always work for very personal items like groceries (eg some folks would prefer to have it organic regardless of cost!)
