hmm? its 9.99 for basic service and "one" character. anything past 1 character is 3$ extra only. so that looks right.
I think you misread the slot charge.
The price for one character slot "IS" 3.00 as they said, meaning every slot over 1 character. Not for having only one.
The first character is part of the 9.99 package and is not an additional 3$.
