Buying "Extra Character Slot Coupon"

It only gives one slot, but when over classes get released, you get the slots for free. I never had to need for an extra slot. I used some NX on expanding storage slots, which is shared between all characters on the same account. I find that a time saver.

My account is new so I missed the bonus from Cygnus (we only have adventurers and cygnus ATM.) and i've already filled up my 3 characters. I don't want to delete any of them since I play all 3 of them actively, and when Aran comes out (which won't be soon, probably May or June) I'll be making an aran. And Evan won't come out for a long time probably.
