Watching how the system chooses deals, applies discounts, and explains outcomes shows whether it's acting in your best interest. Tracking saved amounts versus available offers reveals if the tool genuinely finds value or just promotes certain sellers. Noticing when users override or ignore suggested prices highlights trust gaps. Like analyzing behavior patterns, these signals help improve how such systems communicate and negotiate. Clear explanations, adjustable preferences, and visible comparisons make a big difference. Over time, this builds confidence and smarter automation.
