All orders shipped from April to October will require a cooler pack to be purchased. This is to protect the chocolates from potential melting. Be sure to add this to your order before checkout. If you do not add this to your order, it will not ship. Four half pound boxes fit in this box. If you are ordering more than 4 boxes, add another cooler pack. If for some reason we do not need the extra cooler pack, the money will be refunded to you.Please contact us if you have any questions.
