I've heard that you can purchase Cash Shop Credits with sP. How do you do this?

You'll need to purchase a Gift Card, such as [item2=500 Credit Gift Card] or [item2=1000 Credit Gift Card].

Each is searchable in user shops :)

Buy from other users through their shop, trades, or auctions.

You can buy them in 500 Credit Gift Card, 1000, 3000, or 5000.

Thank you, everyone.
