I've had this issue a few times and it has been fixed in each individual case but it seems there may be a bigger issues as it repeatedly happens.

We will have a product on our website with a star-buy attached and google shopping will read the discount of the star-buy, eg "15% off", and apply it to the price of the item giving a false discount on google. It has resulted in complaints from customers as they've seen the price on google, clicked on the link and then the item is full price on our website. Can this be looked into?
