I have been using the new priority letter stamps and they seem to be delivered really fast. I usually only use them if I post something one or two days late. I have been posting some with and some without so good luck to Australia Post sorting the difference out.

I am guessing they stuffed up the logistics of it all, or it is there for a little wriggle room. As compared to holding something back that doesn't have it.  I am guessing the majority of letters don't use it.

Another thing I have notice with parcels is if it is an eParcel it gets delivered very quickely as compared to a standard parcel. Not only do business' get a better postage rate but they also have 2 standards of service with parcels.

I am also curious as to when they will increase the price again because less letters are sent next year. A basic parcel is $7.80 (i think) and a 500g letter is $5 (with no tracking). Will they increase the price of a letter or reduce the sevice to a few days a week....
