All prices and terms of sale are purely informative and may be modified in response to market fluctuations. However, the order placed through the completion of the purchase process, implies conformity to the price offered and the general sales conditions in force at this particular time. Once the order is formalized, it means the purchase is considered perfectly of right, with all the legal guarantees that protect the purchasing consumer, and from that moment, the prices and conditions will have contractual character, and may not be modified without the express agreement of both contracting parties.
