You must take into account that the shipping cost is higher due to the large size of the article. The different transport companies we work with charge an additional cost for non-standard, heavy or bulky sizes. For this reason, when placing the order, in order not to have unexpected surprises, the system may not be able to calculate the actual cost of the shipment at this time and it is necessary to wait for the final quote from the transport company. Oversized items are excluded from free shipping.
