Choice of Shipping Methods

Up until recently Australia Post had removed the option of shipping CDs overseas as Economy Air Letters, they had to be sent as parcels (much more expensive). I discovered today that things have changed and I can once again ship CDs as large letters to most overseas destinations. Unfortunately eBay does not show Australia Post Economy Air as a shipping option. As a consequence potential overseas buyers, when checking the shipping cost of a CD to their country, see that they will have to pay the parcel rate. I am sure that this turns off many overseas buyers as they don't want to pay $20 shipping (rather than $10, say). Will ebay change its option to keep up with the real situation?
