Thank you for your contact.
Since Zasttra is a marketplace, not an online shop, Sellers run their own store and you're buying directly from them.
Hence, the shipping on Zasttra depends on the seller of the item.
To see the shipping location, please go to the product page of the item you wish to purchase and then on the right-hand side, under seller name, you can view the seller's location to see where they ship from.
To message the store owner: go to one of their product pages or their store page. In the sidebar, you'll see a green button that says "Contact Seller". Click that to send a message directly to them, and they will then reply directly to you.
If you have any questions, please do not hesitate to ask me.
