Chocolate will melt if the temperature is above 70*. When shipping please keep in mind not only the temperature locally, but where you are shipping to as well. Once a package is picked up from us by the post office we have no control over how it is stored or if there will be any delays in the time it is in transit. We will use an ice pack if we feel it is warranted, they last about 48 hours. Ultimately it is your decision and your risk.
