Live price reporting

Often the prices of items are incorrect on this site. As an example today (12/8/26) 300g Nescafe Original in Asda, is £6.00 NOT £7.25 as reported by Trolley. Would it be possible to have a 'live' reporting area, like the Petrol price apps have? The user could change the price or confirm the price as they visit the store. I appreciate there may be regional (or even local variations) but an area or postcode option would be good. Also users could see how current the last price update is.
