No. We do not add sales tax to your order, and nothing is added after it either.
We ship worldwide from our own facility in Europe and we clear every parcel ourselves: customs, duties, import charges and courier handling fees are paid on our side, wherever the album is going. The amount you approve at checkout is the amount you pay, and nothing further is ever collected from your client on delivery.
That is what makes shipping straight to a couple safe with us. A parcel arriving with a customs bill attached turns the best moment of your delivery into an argument about money, so we took that risk off the table instead of passing it to you.
Sales tax on what you charge your own client is still yours to handle, the same as anything else you sell.
