I'm currently sat in Spoons and listening to a conversation about the £2 bus fare.
They were both saying how it will still be considerably cheaper for them to get a day/weekly ticket than to buy singles.

More importantly, they said the way it's been marketed is misleading people into buying singles over a day ticket, which actually costs them more money. To be honest, I can see how that could be the case if you're not too familiar with the tickets available.
