Good health is sacred and with dietary laws still followed today, our line of Kosher certified products allows you to enjoy a healthy and satisfying lifestyle. This pak contains heat-sensitive products and may incur the summer cooler shipping fee (first of May to the end of October). The need of a cooler will be determined based on your delivery address. The eco-friendly, insulated cooler fits two units of product and a $6.00 fee per two units will be added to your order total. For example, one box of Chocolate Peanut Crunch IsaLean Bars and one box of IsaDelight Plus fits in a cooler and the cost is $6.00. If you prefer to not incur a fee, may we suggest that you change your IsaLean Bar preference to Lemon Passion Crunch or Chocolate Decadence.
