Last came on the market for credit cards, retail signs are true to their reputation and often offer their cards at bargain prices, at least the first year. For example, the card is a euro in the first year Intermarché and then passes a 18 euros thereafter. The average price of the card varies between 15 and 20 euros depending on the distributors. The interest in brands is twofold: in addition to customer loyalty (with discounts in the store when a purchase amount is reached) the cards provide a new source of income to super and hypermarkets. For consumers, the interest is not always obvious. Indeed, all cards are always backed by a pool of money like revolving credit, which means interest rates close to 20% when using the reserve.

Finally, it is important to note that credit card purchase in a retail sign does not mean having to change banks. Purchases made with these cards simply debiting the account to which they are attached.
