Essential if the temperature in your area will exceed 70F during the week. Your chocolates will ship in a gently vacuum packed bag in an insulated box with a reusable Gel Blox cold shipping pack. (This helps avoid condensation on the chocolates.) When you receive the chocolates, let them sit at room temperature for 12-24 hours before using a pair of scissors to open the vacuum sealed bag.
If during checkout the USPS shipping option shows 3 days, there will be a (more expensive) option for UPS 2-day delivery available which is better for ensuring the chocolates don't arrive melted.
