Search links are not price sources
A generic store search can show many editions and sellers. That is useful for discovery, but it is not enough to claim a live price for one exact book.
Exact product verification comes later
Price tracking should use verified store product URLs, ASINs, or product IDs. Until those are connected, Books2Buy keeps price labels conservative.
This protects readers
Hiding uncertain prices is less flashy, but it avoids misleading buyers with stale, scraped, or mismatched information.
