Our Ice Packs are designed to last for 24 hours only. Please select this item if you are shipping products when temperatures are above 70 degrees. Although we try our best, cannot guarantee our chocolate treats will not melt when shipped. A $2 additional fee for an ice pack will be added to all chocolate orders being shipped during summertime's warm temperatures. We also pack in insulated wrapping. However, our ice packs only last for 24 hours. If temperatures are over 70 degrees here in Maine OR where the chocolate is being shipped, there is always a risk it will melt. We cannot guarantee our chocolate treats will not melt when shipped. Please feel free to call us and discuss your order's specifics before you order something shipped during the summer.
