I haven't sent anything personally with priority mail in recent memory, but my neighbor has. It took her more than 10 days to get a priority mail package from L.A. to Washington DC. In '96 my wife mailed a package during Dec. from L.A.,CA to Dallas, TX and it took 10 days. I think the rule is send it just plain ordinary 1st class, it will probably get there sooner. Aslo I have been getting SENT 1st class mail mixed-up in my mom's weekly advertisements at her home, of course I send along.
