International buyer wants to return item
Hello! I run a print on demand tshirt/wall hanging shop, I’m in the US. A buyer from Spain bought 2 tshirts that they would like to return due to them not fitting very well. I told them I would accept the return and they would need to pay return shipping per my return policy. I gave them my address, and they asked if they could just return it to the German address they received it from because it would be cheaper. However I would never receive the item back if they shipped it there? I don’t know exactly how the international shipping situation works as my items are shipped by Printful. What would be the best way to handle this?
