Update product prices in cart
first : sorry for my poor english
My products have differents prices depending of the statu of the client. If the client isn't logged the products are full prices. if he is logged, there is a discount applied on some product. So the discount is applied on the products not the entire cart.
My problem: when the client is not logged and he put some products in his caddie, then he log himself, the checkout cart show the product price with full prices it doesn't update himself with news prices whith client's discount. I would like to know if there is a way to update the product prices and then the whole cart.
