Hi joz

Do you list via turbo lister or ebay Sell Your Item ?

When entering postage details -

Click Post to - INTERNATIONAL option

For Large LETTERS you have to click the Flat Rate To All Buyers [this allows you to nominate 4 lots of countries in GROUPS].

Postage for OS letters is pretty straight forward [at the moment]

Any LETTER under 50 grams to USA & Rest of the World excluding ASIA PACIFIC  is $2.35 -

        "         "       "     "        " Asia Pacific, including New Zealand is $1.65

Any LETTER over 50 grams but lighter than 250 grams to USA + is $6.20 - Asia/NZ is $4.50

Any letter over 250 up to 500 grams to USA+ is $14.20 - Asia/NZ is $9.50

So all you do is

1. Click Post to - INTERNATIONAL option

2. Click Custom - this will open up rows of countries - TICK USA/EUROPE/UK & enter [say for up to 250 gram letter] $6.20

3. Click Custom again, a new list, but a replica of first list, will open, click ASIA & enter $4.50

etc.

Hope that helps

Get yourself a  POST CHARGES booklet from Aus post [current one] & at the back you will find all letter rates for OS set out for you.

Good luck,

Most of my buyers end up being from overseas !!! Australians are in turning buying FROM oversears, work it out !!!
