shipping only to the US

I'll ship anywhere as long as tbe buyer pays the shipping. If i do a delivered price in the ad, i'll up it about 5 bucks to the great white north simply because it does cost a few dollars more. I really dont unerstand why leople wont ship worldwide. I dont waste time going to get a shipping qluote, i get them online. Sometimes i am a couple bucks low, sometimes a couple bucks high. It all works out in the end.
