This probably isn't anyhting new. I haven't checked EVE Online forum about it yet. 

Approach a base. Initiate a docking procedure. Bring up generate cyno field dialogue box. When you see the box saying you are entering hit the box immediately!

You will dock. Your cyno will stay until downtime. You can get your freighter through it for unlimited amount of time, creating endless streamline of transportation bringing in endless eve isk.

 

Forgive me if this is not new. 

If not, heh oh well.

This goes hand in hand with the previous post I mentioned about saving a ship. Try calculate how much you save and made then Compare ISK Price against the USD.
