Who knows why they do what they do. I recently ordered a non-gun related item (still about $200) that went from Florida to Phoenix AZ, sat there for over a week, then finally came to St. Louis.
A few years back I sold a knife on a forum, before all the tracking was automated. About four hours away if I'd have driven it there myself. Told him I shipped and as sales sometimes go on forums, I never heard from the guy and figured all was well til a couple weeks later he asks where his knife is and heavily implied that I didn't ship it. I sent him a pic of the receipt and tracking said it had been sitting in his local PO the whole time. They delivered it the next day.
