On the Exchange, people regularly say US shipping only or lower 48 only. Even if the buyer pays for shipping they often don't want to ship it outside the USA. Why? Canada is on a land border with the continental US and it is not an inconvenience for the seller to ship a knife here in any way. I don't understand why so many sellers still refuse to ship outside the US. Why is this? It makes no sense to me. Thanks, From a friendly Canadian just wanting to purchase knives from our southern neighbours.
