Scopes coming out of the U.S. require U.S export permits.
You need to get a Canadian import permit in order for the seller to obtain the U.S. export permit.
Most E-Bay sellers do not bother with the permits, and therefore can end up in a world of trouble with the U.S. authorities.Your scope can be seized on the U.S. side (and you will lose it and your money), and your name can be flagged by the U.S .authorities which may bring closer scrutiny on future purchases.
If you are posting about U.S .purchases on CGN, the policy is that both countries import/export laws MUST be followed, or don't both posting.
