Well I figured it out...I think. Every piece of equipment sells for 10x the amount of points it costs.

I just bought a sword for 1600 RoE points (or whatever they are called) and it sold to a NPC for 16000 gil.

Well, I guess gil is no longer an issue anymore!

You can also warp to homepoint from any other homepoint. Traveling is insanely convenient now. It's like the game is on easy mode!
