This paper aims at analyzing consumers’ preferences towards olive oil attributes taking into account the retail chain where they buy food. The methodological approach is based on the design of a choice experiment using home scan data from a sample of Catalonian households. Four attributes are selected: price, brand, type of olive oil and packaging size. Two retailers are considered with different business strategies: Mercadona and Carrefour. Results show that the preferences for olive oil attributes are different depending of the retail outlet a household uses to buy.
