Purchase conditions or service contract

Prices do not include VAT (21% in Spain) and do not include shipping costs.
You can consult and request the data sheet of the works before purchase.
The purchase is effective with a minimum refund of 80% of the stipulated price before the product is delivered (products only, not services).
A minimum period of three days is stipulated for shipments.
In case of return, the buyer will bear the shipping costs.
But, above all, this server-client relationship, due to the type of good and service offered, must be a clear relationship, open to suggestions and fluid from the beginning.
