Goods are despatched from Poland after receipt of payment. Postage for a doll is €10; postage for a doll bed up to 2 kgs: €15. for the larger beds or other wooden items postage is €25.
On average, the mail to North America takes 2-3 weeks for a doll or doll bed; within Europe: 1-2 weeks; Australia: 3 weeks. But mail can be faster or significantly slower, especially in December due to the Christmas rush.
Buyers are responsible for any customs fees, taxes, or receiving fees incurred. Though I never saw that anything of the sorts had to be paid, theoretically it can be possible in your country.
