Trading

Trading is the act of giving and/or receiving items between two players, or between a player and an NPC. Giving an item without something in return or getting an item without offering something yourself is also called trading in Diablo II.

When trading with other players, gold is rarely used as a currency. In Diablo II runes, gear, charms, and jewels are the most commonly traded items between players. The most common currency is often runes, as these usually have a fixed value and are necessary for some of the most powerful equipment in the game.

Diablo III
In Diablo III, trading was fully implemented in the vanilla game (both personal trade and Auction House), but with most, if not all decent items becoming Account Bound in Reaper of Souls, the trade between players has mostly become obsolete. Gold also cannot be transferred anymore.
