There are various differences between the way we provide our necessities nowadays and the ways our grandparents did it many years ago. Appearance of big stores has played a magnificent role in this regard. Providing a long period of time, vast area, and right to choose articles freely from the shelves are the most important characteristics of this kind of sale. From jurisprudence point of view, the time of concluding contract and passing liability is very important to be discussed. One of the most remarkable questions in this regard is that if an article damages while it is in the cart of buyer, who should pay for the damage: the buyer or the store? The first step to answer the question is the interpretation we have from taking goods from the shelves of the store. If we consider it as offer, then no contractual responsibility can be recognized and general principle of tort law may result in responsibility of the buyer. But if we interpret it as acceptance of a unilateral contract offered by the store, then we can benefit the advantage of some sort of contractual responsibilities.However, taking into account the aim of providing such a vast area for shopping and unfair contractual position of the parities, it seems that it is not acceptable to consider responsibility for the buyer while she was acting reasonably and without fault.
