Discount Card

An item, ability, or situation where a character can purchase items at a discount at shops.

In some older Video Games inspired by (or based on) Dungeons and Dragons, having a high Charisma score would cause merchants to charge you less for items. Alternately, some RPGs allow you to negotiate the price on goods, and having a higher skill in the bargaining department may be able to get you the goods at a lower price than usual.

Also, this tends to be one of the perks of a Hundred-Percent Heroism Rating.
