Re: STUDIO SCALE TIE FIGHTER **UPDATED PICS**
I use USPS online all the time - a dozen packages a week sometimes. Never had one problem, especially like you describe. I love the online system too - saves time, especially when I send stuff to Japan (which is often!). I send model kits to Italy (which is notoriously flaky with packages), Germany, Spain, Canada, and Australia mostly. I require the buyer to pay for priority or EMS shipping. It's way more expensive, but it gets there within a week and is traceable. Man, you have had some bad luck with shipping-related hiccups - even in your new area post-move! I can maybe see it being a bad luck of the draw with a regional branch (there's a particular post office in Baltimore that I avoid like the plague - the staff are morons!)... but you're in a new area now, right? I hope you get better luck.
Do you get/provide tracking numbers? If not, do that from now on, with every single thing you send - that way, USPS is more accountable. Right now, it's "you said/they said" and it gets you nowhere when you need to prove shipment.
