Hi guys,
This is a common issue on many trade forums, not just the watch sites. I'm a pro scale modeler and ship model kits all the time around the world. So I'm just throwing this out there, because there is a lot of misinformation about shipping especially with USPS.
You can ship almost anything -- given a scale, printer and paper from the comfort of your home without ever having to set foot in a PO again. From the USPS website you can order (all for free) boxes, custom form clear sleeves, Priority Mail stickers (for brown boxes), and all the Priority/Express Mail boxes your heart desires including the new Flat Rate boxes.
To weigh an item with a normal bath scale, take your weight and minus it from the weight of you + package. USPS only requires the lb, as they use a simple 1-2lbs, 2-3lbs, etc. class system for pricing, so bath scales are close enough for anything over 1lb.
With the weight, box size and address you can then go online and have the label easily and quickly printed out which you then tape to the box. Now use their handy FREE pickup system and schedule a pickup. My postman will gladly take any package ready to go, so I don't even need a Pickup request, but as long as it is not on a Sunday they will pick up any Priority package at your request.
Now the one thing most people are not aware of is the Priority Mail is basically worldwide blanket coverage. So that means you do not anything special to send it overseas, as long as the buyer will pay for shipping the process is absolutely no different to shipping CONUS. As long as you have the clear sleeve in hand (form 2976 I believe), so order a set of 25 from the website and then you can ship to anywhere USPS ships. The customs form label will be completely filled out on the computer--including proper time stamped, and even add your name to the sig. box, so there really is no more need to go to the PO.
Here is the link to the Priority Mail supplies page, note all is sent to your home for No Charge.

It is actually very simple and quite efficient service and there is no longer any requirement to physically go to the PO to ship overseas. Any mailman will then pick it up for free. If they say no, complain to your local PO, it is the rule that they pick up any Priority/Express mail package for free regardless of destination. Parcel Post is worthless and wouldn't waste my time, but as long as you have at least one Priority Mail package going out, they must take the Parcel Post package too.
I hope this helps to clear the mis-info on USPS shipping. I am almost certain UPS/FedEx/etc. will also provide a very similar free label and pickup service, so you have options.
I've shipped to the "bad" country lists under the new system and as long as it is fully insured, have no had any problems (knock on wood).
HTH,
Mike
