Hi, I live in WA and understand it's legal to purchase a firearm in a border state (i.e. Oregon). In WA all FFL's charge a "usage tax" which so happens to be similar to the 9.3% sales tax in this state. This can greatly increase my total cost of an expensive firearm. So Can I A) Have a firearm shipped to an FFL in Oregon and legally purchase there? and B) Will the Oregon FFL charge me a sales/usage tax like WA? If it's legal and there are no other fees charged other than the transfer fee, it's worth the drive to me. Thanks!
