If Koodo always had sales then they wouldn't be sales & koodo wouldn't make money, remember koodo is a business and it needs to make money sometime. If you want coverage to expand and the network to grow and better things to come to the company to offer its customers then you can't expect to pay nothing all the time. Anyways koodo could have some back to school deals coming soon we'll have to wait and see. Keep an eye on the website and Koodo's Facebook page for announcements on specials, deals, new devices and other info.
Most likely in the next week, if not today. Most of their promos are done on Fridays, and this is around the time that carriers start offering the Christmas deals!
