Not to beat this to death - we're just chatting, right? International packages cannot just be dropped off at a US Post office. You have to go to the window and have a clerk check them in even when you've printed a label and customs form, just as if you're sending a domestic US Express or Certified mail.
I'd still be interested in an example where a buyer made a deal then have the seller suddenly say, "an extra 10 dolla, please." Maybe the seller quoted a price without knowing it was shipping out of the country.
No problem. Below is from the eBay shipping center; you can ship internationally online.
It's the extra $$ put into the shipping fees for international - it's quite obvious comparing shipping rates from USPS to the sellers quote; it's easy to see something that goes beyond the normal shipping and handling $$. The seller has the right to charge whatever he feels to add to the shipping fee he pays as a handling fee, our point is that some times that the handling fee charged is little excessive and not, at least in our opinion" fair.
International Shipping FAQ's
Q:\tFor USPS, should I use Priority Mail International or International First Class to ship internationally?
A:\tWith Priority Mail International (PMI), you can use the same USPS free domestic box, you get free Delivery Confirmation, and you can print the labels from PayPal or eBay. You'll print 2 pages and insert them into the USPS-provided plastic envelope and affix it to the box. You can now have the package picked up or drop it at the post office.
With First-Class Mail InternationalÂ® (FCMI), the fees are lower for the buyer. However, FCMI is not an option on PayPal or on the USPS website for label printing on the site. To use FCMI you'll need to provide your own box, and mail the package at the post office. A registered mail fee will be charged to track the package.
Q:\tCan I drop my Express Mail International item or other USPS international packages in a collection box?
A:\tExpress Mail International and Priority Mail International items that have the mailing label, customs declaration (including an electronic round stamp), and postage prepared and paid online through Click-N-Ship service on USPS.com, through the eBay/PayPal integrated shipping solution, or through an authorized PC PostageÂ® vendor Web site may be deposited a collection box, lobby drop, Automated Postal Center drop, Postal Service lobby, or be picked up by a letter carrier.
