It matters :)
Because if they are exped with an other char in party, or manually its fine.
BUT if you plan to exp them with a BOT, then the thing becomes serious, because there is a real chance to get banned if someone reports the char.
Also, Im sorry to say that your service seems to me not professional at all, yesterday you had DIFFERENT (lower, nearly the half) Prices, now you doubled them. Im sorry, I will not do business with you sir.
Kind Regards.
