After investigating this for you, I have found that the price increased for you by €20 when logging into your account with a home address in Denmark because of VAT rules in Denmark. Prices differ on our webshop per region due to VAT, which is why the price increased by €20 for you. We thank you for your understanding and we are here if you have any other questions or concerns.
