Postage service Small Parcel With Tracking(1519) is not available

I keep getting an error when trying to submit an item to Ebay Australia.

Error says: “Postage service Small Parcel With Tracking(1519) is not available.”

I do have a shipping option of “eBay Australia Post Flat Rate 500g Satchel + Signature” but NOT “Small Parcel with Tracking” which appears to be an old defunct shipping option.

I can see in the the text mentioned in the error as an old shipping option “Small Parcel With Tracking (Discontinued)” but my selection IS NOT this one.

It appears to be associating the new postage category with the defunct one if the error text is correct.


See screenshot of options:

I have GS 6.8 (586) because I am still on Snow Leopard.

This problem might be fixed in GarageSale 6.9.
Any chances you update your Mac to OS X 10.9 Mavericks or 10.10 Yosemite?
