I don't see why you're grumbling.

Well basically I'm grumbling because hundreds of my listed items have the option AUSTRALIA POST REGULAR PARCEL + TRACKING  and I read here on the boards - not from ebay -  that

(a)  the option has to be removed

(b)  there is no way to do it in bulk

And I am also grumbling that I did not see or receive an ebay announcement about changing it being compulsory

AND if they don't want us to use the option, why is it still there?

AND grumbling makes me feel better.:-)
