We certainly do ship overseas, and will use the shipper of your choice, or the one we have found takes the least amount of time clearing your customs. Shipping internationally is not cheap, and canvas can be heavy, but we’re happy to ship if you want to place an order.  In the US we generally use UPS for our shipping, and they can not ship to a PO Box. We’d much rather ship to a physical address, as we’re shipping a physical tent. Give us a call if you need to make special arrangements, we’re a small shop and will certainly try to accommodate your request.
