WHY do different bus companies charge such different prices for the same journey?

I often catch a bus from centre of Totton into Southampton and Solent Blue Line charges £3.80, while Wilts and Dorset charges £3. They take exactly the same route and I cannot understand why there is such a big difference.

We are encouraged to use public transport but at these prices it is no wonder people prefer to use their cars.

As soon as I have passed my driving test I intend to stop using the buses.
