Bloomfield has a municipality-run jitney (divided into two areas, north and south) which connects to four trains at Bloomfield Station in the morning, and five in the afternoon, rush directions.

That might work for you, but Allwood is a great option too.

It’s effectively $0.50/ride, although you buy a punch pass of 50 rides for $25 (nonexpiring)
