The return policy is inconvenient—you have to package and send the items back yourself and also pay for shipping to the return center in Spain.
I also feel misled, as the website clearly states that prices include tax, yet I received an additional tax bill afterwards.
I bought three items and am returning two due to sizing issues, but I still ended up paying import tax for all three items, in addition to the return shipping costs.
The T-shirt itself cost €37, but I paid approximately €30 (350 NOK) for return shipping and about €50 (570 NOK) in import tax. In total, that means the single T-shirt I kept ended up costing around €117.
This is by far the most expensive T-shirt I have ever bought.
