Cheapskate
Cheapskate (Minor) by Senator Cybus
A strange and lucrative power that subtly alters reality in favour of the super being's bank balance: anything that the character buys, regardless of the price or the method of payment, will cost him far less than it should. Somehow, events will always play out in a way that saves the hero money - the pizza delivery boy will miscount the cash he’s been given, PayPal will mysteriously malfunction, etc.
The super being enjoys a discount of 5% per level on any and all purchases that he makes (5% at level one, 10% at level two, etc). The power works for both one-off payments and amortized purchases.
Limitations: The hero cannot share the cost of an item and still receive the benefit of the power - only items or services that he purchases by himself gain the discount.
