You need to be ready to spend a lot if you want to travel conveniently by waypoint, especially if your intended destination is across the map. However, there are a few tricks you can use to save some money. If you die, you can appear at the waypoint of your choice without paying anything. You will eventually have to pay a repair bill if you rely on that particular trick too often, but it is otherwise useful and quite affordable. Another option is to enter the PVP area and journey to The Mists, where you can swiftly catch a warp to the capital city of your choice. Finally, travel within capital cities is free, so you don't have to cross one the old-fashioned way if you're in a hurry.
