Public Mobile today announced a new promotion where each person that you refer will earn you a CA$20 credit.
There is no limit to the number of friends you can refer, so the more friends that join, the more you save. Plus, if a friend joins before September 12th, they receive their 1st month free and 50 percent off selected handsets (see http://blog.publicmobile.ca/blog/2010/08/23/50-off-select-phones-your-first-month-free).
The CA$20 credit will appear on your account within six weeks, provided both accounts are in good standing.
The offer runs until September 30th.
