Cash Shop Credits are the local currency used for the Cash Shop. CSC can be purchased with real money (eg. $USD) and come from the "Credits" tab in the Cash Shop. CSC are deposited into the users account upon a complete transaction and they will also receive a coupon in their sMail when they purchase 2,000+ credit with Paypal.
Credits can be redeemed from item-versions called Credit Gift Cards. These cards can be sold to other users so that they can get Cash Shop Credits without spending actual money. Credit Gift Cards come in 100, 250, 500, 1000, 2000, 3000, 5000 denominations.
At times, Subeta will have a special sale and users will be able to get special items when purchasing CSCs. These can only be received when purchasing through Paypal or Braintree.
