Does anyone know the fare from Baranquilla to Cartagena by taxi? Thank you!

a private taxi you get for 140.000 - you can get shared taxis , they take 1:15 Cartagena to Baranquilla

sorry i forgot to say , the shared taxi charge 19.000 pesos - they pick you up in the hotel you are staying in Cartagena

So 140,000 is about $80 USD. Is that correct?
How could I arrange a shared taxi in advance for cheaper?
Thank you!

I just used the Marcol service from Cartagena to Barranquilla, and they're really professional. But understand that they don't go to the airport in Barranquilla and drops you off in a neighborhood in El Morillo, which requires you to take a 20 minute cab ride. So plan accordingly.

I´ll use them next friday from Cartagena to Barranquilla $ 25.000 COP. Door to door service (that's what they have said and I hope so).
