They've abolished the 125g weight band for letters, so rate goes straight from $2.35 for 50g to $6.20 for 250g and then $14.20 for 500g.

So the 50g rate's the same, 500g has gone up, 250g has gone down, and anyone waning to send a 51g letter will feel the pain as the 125g weight band has gone. And of course, the prices have officially become a dog's breakfast as they are no longer simple multiples of the 50g rate...
