Hi Joanne: On their website, it is $45/2GB (which is the same as Koodo right now) Promotions are based on location, time, and your history with Koodo. If you see an ad of a competitor locally, you could try to ask a local Koodo kiosk to match.
Besides promotions which are usually for new customers, by all means call them up to ask for what you see being offered elsewhere or currently for new customers. Your history with Koodo might even get you a better deal. Give them a call.
