Macau Post increase the postage rate, starting from 25 June 2014. On the cover, I just affixed a "The New Campus of the University of Macau" stamp of 2 Patacas out of the normal postage of 3 Patacas. On 18 September, I went to the GPO to get the mail and paid the postage due. The postage due should be : ((1 / 3) x 2.3) + 4 = HK$4.8. On the cover, you can see the round-shaped T 1.00/3.00 postmark from Macau and a Hong Kong "To Pay" chop.
