Shipping on puzzles is included in the price. Shipping on paper is $10 per order. For international shipping, please send me a message and I’ll calculate it. In my experience, you need to expect $20-40 to ship to Europe but sometimes I can ship more than one puzzle for that price. If you want a puzzle that is listed as sold out, just send me a message and we can discuss a custom order. Every puzzle is custom made for you except those listed as Ready to Ship. “On backorder” notifications (which you won’t always get) simply mean I have to make the item for you. If paper is listed as sold out or on backorder, it isn’t currently available.
