Is There a Costs Money Limitation?

[Gef]

I use this in a TL3 game; scale appropriately for higher TL:

-10% for a material component that nominally costs a buck, but can be scrounged or made.
-10% more per order of magnitude more expensive: -20% for $10, -30% for $100.
+20% for an item that's not consumed, e.g., net -20% for a $1000 wand or holy symbol
