Hi, folks! Looking for some advice.

What are some good, affordable shipping companies for moving overseas? I went to send a 3.6 lb package to a friend in Italy the other day and the USPS wanted $30! Dang! It's my intention to take 3 bags on the plane, plus carry on, paying for the extra bag. That will get most of my essentials over there, but I'm sure there will be some things I still want to keep that won't fit. I'm a reservist in the Navy, but since this isn't an active duty thing, I don't believe I can use military shipping options. I might be able to convince them to send my uniforms, though, since I'll still be drilling over there.

Ideas and recommendations? I see lots of companies on the web for this kind of thing, but personal recommendations would really help me sort through the chaos. Thanks!
