Now I come across probably my biggest downfall: the fact that the 10% discount doesn't apply to International Economy Parcels. 99% of my air mail parcels are economy so this is a big disappointment. 5 parcels a week (10% discount) I can do but not 10 parcels a week (12.5% discount). And here I was hoping for much needed discounts on my expensive economy parcels to places like the UK and Brazil and France and other expensive countries to post to ($22-$25+ per 500 gram parcel). Again, big disappointment.

Again, thanks for the info in your posts.

Hi again,  are you sure you are using International Economy Air.   There is no tracking available on the economy  air Service.

International Standard Post  does include tracking .  And the Discount postage applies.
