# Buying & Selling

In-game businesses staffed by Non-Player Characters (NPCs) and [Vendors](https://whitepaper.paydirt.game/vendors) will buy from and sell to players the types of [game items](https://whitepaper.paydirt.game/virtual-items#game-items) they stock or are interested in buying.\
\
[virtual-currency](https://whitepaper.paydirt.game/virtual-currency "mention") is used for all in-game transactions.\
\
Players may also buy and sell in-game goods and services with any form of gold by its *weight*, by its *face value (applicable to* [gold-coins](https://whitepaper.paydirt.game/virtual-items/collectibles/gold-coins "mention")*)*, or by *pinches (applicable to* [gold-dust](https://whitepaper.paydirt.game/gold-dust "mention")).\
\
The in-game buying & selling interface supports all of the above forms of payment. \
\
NPCs give change in the form of [gold-dust](https://whitepaper.paydirt.game/gold-dust "mention") or [#spanish-reales](https://whitepaper.paydirt.game/virtual-currency#spanish-reales "mention").\
\
Outside of the game, the [Paydirt Marketplace](https://whitepaper.paydirt.game/marketplace) can also be used to buy and sell.
