I have ordered many things from overseas over the last 15 years. I have never had any problem with airmail post - and it is delivered right to my door!
Unfortunately, a few times US suppliers have sent things via a carrier service - FedEx or UPS. Without exception, this has cost more and has had associated problems (like, I have had to go to their depot and pickup the parcel ... or there would be an extra charge, fer chrissake!).
You will be amused at my latest experience. A friend of my daughter's who lives in Hawaii sent me a bag of Kona coffee as a gift. Delicious! I liked it so much, I went and ordered some more from the company's web-site.
The cost of the coffee was US$14.95 ... well, not cheap but hey! this was a treat. Unfortunately, their web-site could not specify the shipping cost - so I assumed it might be US$8 or $10 for airmail postage.
When the coffee arrived, I found they had charged me US$22 for FedEx delivery! This is 150% of the price of the bloody coffee!
Furthermore, a week after it arrived, I got a letter from FedEx saying I owed them A$47 for the "Quarantine Inspection Fee". So I sent the invoice back to the Managing Director with a note saying as I hadn't authorised them to pay this fee, I wasn't going to pay it.
So I suggest you always state Airmail Parcel Post when you get stuff sent from overseas.
