If you're travelling off-peak, you can get this down to $22.50.
You can get it for even less by buying Elizabeth-NYP tickets and buying a turnstile-only ticket for the AirTrain (available only at EWR):
EWR AirTrain pass: $5.50 (x2)
Elizabeth-NYP: $5.50 (x2)
-------------------
Total (R/T):
$22.00
If you're traveling off-peak, you can get this down to $20.25 by buying an off-peak roundtrip Elizabeth-NYP ticket.
Note, however, that I don't think you can buy an Elizabeth ticket from the machines at EWR, so if your first point of contact with NJTransit is at EWR, you'll have to pay slightly more for
nerd's approach.
