Try shipping USPS flat rate regional. I have shipped all over the country using it. Cost a little more than local but not much. In Oklashoma you can ship a lot of stuff in a small A box for around $8.50.I sold a bunch of knives on bladeforums last week and the shipping ate all the value up. About 20 for each item.
I would put my name in but I was recently given a great knife, only ammo I need is 5.56, and the only parts I need are for a mini 14.
