Be careful with carrefour while purchasing promotion products. I had bad experiences 4 times. They were showing promotional price near to the product and while billing it is the actual price or more. It happened for me on toy, perfume, laptop and cosmetics on different stores and they refunded me the excess in 2 cases when I contact customer support and 2 time didn't. So please ensure for the price while billing where there is a chance of ignorance while we have many items in our cart.
