Yesterday I got 3 Peggo cards – for me, Jonathan and Charles. 
For the past three years I’ve been buying the monthly passes, mainly for the convenience of not having to go back more than once to the shops. When our family would be out of the City for long periods of time, I would just bear the wastage (sometimes 15 days out of 30/31 of the month).
But voila! Here comes the Peggo cards. It all makes perfect sense: you can buy the cards online or at designated sites (like Shoppers); same goes for loading cash into it. You can go to outlet stores or after registration online, you can put money into it as much as you want or need. In short, you can decide instead of being locked into a weekly or monthly pass. Progress, it is!
