Trading, Vending and Zeny

Zeny is the game's currency; prices written with a "z" are in zeny. Most zeny enters the game when players sell items to NPCs, and the usual way to grow richer is selling to other players through trades and vending. Valuable items can also be hunted or earned from quests.

• One character can hold at most 2,147,483,647 zeny, so many players stay at about 2.0 or 2.1 billion to keep trading smooth.
• A trade is cancelled if the zeny would push either player over that cap, and one trade can carry at most 999,999,999 zeny.
• A vended item that would put the seller over the cap cannot be bought.

The Merchant and Super Novice skill Pushcart (10 levels, needs Enlarge Weight Limit 5) lets you rent a cart from most Kafra employees. The cart holds 8,000 weight in 100 slots and opens with Alt+W, but slows you down: you move at 55% speed at level 1 and at full speed at level 10.

Vending (needs Pushcart 3) opens a shop that sells the items in your cart to other players. Higher skill levels allow more item stacks, up to 12 at level 10.

• Highest price per item: 1,000,000,000 zeny (some servers stop at 99,990,000).
• Items priced over 10,000,000 zeny pay a 5% fee, so the seller receives 95%.
• You must stand at least 4 cells away from any NPC to open a shop.
• Offline vending works through a separate usable item and sells from your inventory; its earnings arrive by in-game mail.

A Buying Store does the opposite of vending: you list items you want and the zeny you will pay. It can show up to 5 items (2 for non-Merchants), you must already carry one of each item, and only etc. items and consumables that were not brewed can be bought this way.

• Non-Merchants: buy one-use Black Market Buyer Shop Licenses (500 zeny each) from the Black Marketeer in the Morroc pub.
• Merchants: pay 10,000 zeny to the Purchasing Team in the Merchant Guild of Alberta to learn Open Buying Store and get 5 Bulk Buyer Shop Licenses; more cost 200 zeny each.

The Auction System let players auction costly items in halls in Prontera, Juno, Lighthalzen and Morroc, each hall separate from the others. Auctions ran up to 72 hours with an hourly fee, and prices had to be between 10,000,000 and 990,000,000 zeny. It was little used and is currently disabled on iRO because of bugs with the mail system.

The Kafra Shop is iRO's item mall, paid with Kafra Shop Points rather than zeny. It sells consumables, headgears, boxes, costumes and rental gear. Do not confuse those points with the Kafra Points earned from Kafra services.
