Bus service around Southern California for $1 for booking in advance and
online.

Price range from $1 and up depending on destinations and advance purchase.
Just recently took a trip from Los Angeles to San Diego on the bus . Pay
only a $1 for one way trip. There was wifi on the bus but it was really
spotty.. so probably not worth bringing your laptop.
Looks like the company is an affiliate of Greyhound, so not the best service
and not the best bus stop locations but I needed it last min trip down to
San Diego
