Pieveregina - Apicoltura Biologica - Azienda agricola Carlo Alberto Avanzolini review for Google & YouTube

I sued this app and is really easy to use and straight forward to start on Google Shopping. However I do have some errore on Google Merchant that check differences between the feed price and the website price even though there aren't. Google Merchant assistance says it depends on the code on the website that confuse Google Crawler. Can you help me out guys?
