What's the best way to send stuffs over to Europe

If you have a business, you can use BAX Global but they will not pick up at a residence.

Actually you can track your package through USPS if you use the Express Mail International service. If you however decide to go with the less expensive Priority Mail International service the number on the Customs Declaration form can be used to track the package.

I just recently sent a heavy amp 100Lbs to England and used FED EX International Economy. It was the cheapest but still rather costly however the buyer paid. It arrived in excellent shape in 3 business days and I was able to track it all the way.
