No, the "Bonus" and/or "Exclusive" boxes are not part of the regular monthly subscription.  They will carry a premium price over the regular monthly boxes, typically because they contain exclusive items or a greater amount of products.  These boxes can not be reserved without payment.  They are also sold in limited numbers and once they are sold out, they will not be offered again.  If someone purchases more than one by accident and the item has not been mailed out, the box can be canceled before it is processed but the buyer will be assessed a 20% processing fee, no shipping and handling fees will be returned, and the refund will be issued as a virtual gift card.
