5 years ago my standard padded envelope I ship my decals in was 99 cents to ship. Today the same envelope under 2 oz is $3. WHY???
If the Trainz shipping is really what they charge for shipping outside USA...maybe twofold:
They don't want to ship outside USA
With new credit card charge back rules they may need to prove delivery with signature....which is very expensive outside USA.....maybe not $700...
