Are you European?
Our system needs to know where the customer comes from to apply the corresponding type of tax. That is why, if you are a new user or are entering the website without your registered user, you will see the prices without VAT.
It is necessary for the client to register and enter with their user so that the system recognizes where said client comes from and applies the corresponding tax, which will be 21% Spanish VAT for all clients from Europe (for those from outside Europe does not apply this tax).
Therefore, we recommend that all customers access our online store with their corresponding registered user in order to see the correct price of the products at all times.
