Guild Wars 2

Merchants could offer kind of a transit pass. An item that would sit in your inventory with a number of charges. As long as you have charges remaining, Waypoint travel is free(as you’ve effectively paid ahead of time). Suggestion of 1g for 50 charges.

Alternatively you could make such an item allow free waypoint travel for a certain length of time, countdown starting from first use or from moment of purchase.

50 way points for 100 silvers means 2silvers per waypoint.

not really worth it for short distant waypoint travelling but for long distance it is worth it.
