I just got an email from Midway this afternoon stating that they will now offer shipments by USPS Priority Mail flat rate. I have no idea why it took so long but I suspect they had a contract with UPS prohibiting such service. UPS and FedEx both screw us Alaska residents in this manner.
For those of us ordering bullets or other heavy dense items this should be a real $$ savings. I'm sure Midway's competitors will follow up also.
