Why can't you guys just admit you didn't at all think this through?

Would that make you happier? The truth is, yes we have no definitive system for exactly how much one thing to the next costs. Lien is based on Yen which means that one Lien is roughly equal to a cent. Use that to make an educated guess on exactly how much you would spend on certain items or what materials would cost you.

We could make a shop to have consumeable equipment like grenades to be used in missions or health kits, little armor upgrades that can make some missions more forgiving if you mess up like a one-time activating shield on a fatal hit, afford companions or pets, or even upgrades for them. There are loads of things you can do.

And best part? Everyone can buy them. Everyone. We can look at a mission, and think about if we need any of the consumeable equipment, and buy it if we have enough money.

I can go into more depth, but basically this will add more meaning to getting lien back from missions.

We're trying to make a slice of life RP with monsters and action sequences, not a video game. I'm not really seeing the idea of adding extra lives as buyable items as a productive idea.

Money is a necessary part of almost any society. We trust that each roleplayer isn't going to abuse the monetary system simply because there is no precedent set. For instance Sapphire has a rather sizable trust fund but you don't see me going around buy atlas military tanks and high powered explosives even though she likely could afford it.
