The Cash Shop is a function where players are able to buy in-game items with real money.
The Cash Shop sells a variety of unique items that characters that have many different uses. Players can buy clothes that mask over their equipment, such as overalls, shirts, pants, skirts, weapons, gloves, rings, shields, capes, and hats. Other items sold include special effects, wedding tickets, store coupons, pets, and plenty of other useful items. Most of the items in the Cash Shop are only temporary, and will expire after a certain amount of time (usually 90 days).
NX Cash can be purchased using real money at department and convenience stores, or with a credit card. As MapleStory is a free game, the Cash Shop is Nexon's primary source of income from the game. Despite this, the Cash Shop remains completely optional, and it is possible to enjoy MapleStory without using the Cash Shop.
