In order to solidify their image of having the lowest prices, Carrefour announced with great fanfare at a press conference about six months ago that it would refund the difference if another store turned out to be selling a product at a lower price. They declare the refund policy on big signs in their stores and on their bags so that their customers won't forget.
為了鞏固價格最低的形象，半年前，家樂福大張旗鼓的召開記者會宣示「買貴退差價」的策略，賣場裡大招牌和購物袋上都清楚標示，時時提醒消費者。
