Wayne,
I set ebay to Express mail for International which is the most expensive b/c it is tracked and insured and protects me with Ebay/Paypal. It is just not worth the headache any other way when dealing through ebay, I have had too many "lost or damaged" packages going to International destinations.
On direct non ebay sales/trades, I can ship first class if under 4lbs and that still is not cheap, but figure $20 gets you a single figure. however, I only accept paypal friends/family, or postal money orders if I do that b/c I don't want to take the responsibility for untracked shipments.
Long story short, it is not cheap to ship at all, Amazon ruined a lot of expectations as everybody is used to free shipping or cheap shipping, but the reality of the actual costs are much different.
