You should go beat some people up and steal their VIP Coupons.
There's a way to get free Coupons through Nexon.
Just don't play for 30 days and then go into the Free Market, press "ALT + ENTER" and click the "X" button on the game.
Then a thing will pop up offering you two random cheap items (Usually Vicious Hammer + Owl of Minurvia) and a VIP Coupon (May not be the Skin coupon though).
Pretty sweet deal.
