Nevertheless, since the Website may be visited simultaneously by various Users, it is possible that more than one User purchases the same product at the same time. In these cases, the Product may appear as available for a short time, even though it is actually out of stock or momentarily unavailable, since restocking is necessary.The Website contains information relating to the availability of each Product.Should the Product be unavailable for the aforementioned reasons or in other cases of unexpected unavailability of the Product, without prejudice to any other legal rights of the User, the Seller will immediately inform the User. The User will therefore be entitled to terminate the agreement.Alternatively and without prejudice to his/her rights, the User may accept: an extension of the delivery period; a product of equivalent or higher value (in this case, upon payment of the difference, and upon express acceptance of the user).
