I've only used a Presto card for a few days now and I can say that I have a love/hate relationship with it. Although you can do many things online, there is such a huge time delay before those updates happen that it makes online transactions useless. Instead, go to a GO station and perform your transactions there.
Pros:
- Saves me $0.50 per trip to use Presto over buying tickets.
- After 36 trips in a month, prices are drastically reduced.
- After 41 trips in a month, trips are free.
Cons:
- Presto cards are sent out before they're available to use. It was 5 days before I could use mine.
- Hit and miss with the customer service phone number.
- It takes 24 hours before online reloads take effect. Come on... I can reload my Starbucks card online and immediately walk to a Starbucks store.
Tips:
- Perform any and all transactions at a GO station. They take effect immediately.
- Make sure to set a default trip so that you don't have to tap off.
