I wish that were the case.

Curious, because all the letter rates are 'fixed' variables (ie, not calculated like the parcel quotations), so the only way it could really overcharge is if your 'large letters' are actually being quoted as parcels, which will be the 'default' unless you either change the default dimensions, or explicitly define your items with accurate dimensions (as mentioned elsewhere in this thread).

In that case, you are 'correcting' the wrong thing. You should be trying to get the weights/dimensions right to classify the item(s) are large letters, not trying to compensate by introducing negative handling fees.

You have something fundimentally wrong somewhere. Although I'm no expert on how the weights are actually calculated (as per the 'weights.txt' file this is not a function of the AustPost module) but I seriously doubt it'll be giving you different weights depending on country of destination ;-)

As I said, you have something fundimentally wrong somewhere, and I'd not even like to guess what or where.

Not really, but I also can't fathom what scenario would require you to use negative handling fees in order to obtain a valid quote.

Something is 'odd'.
