They overestimate shipping costs, charge a 15 euro fee on top of import vat and will not adjust this amount unless additional fees are paid. after confirming thee is an overestimation of shipping costs(amounting to a doubling of the actual vat i should have paid), they said they could resubmit the customs form but would only do so after a 50 euro fee for doing this.
