We only use overnight couriers or express post to send chocolates. We don’t use regular post or road couriers whom take days to weeks to deliver so it is more expensive. In fact, the current cost to send parcel post is a fraction less than sending express so it would be less than $1 saved if we sent parcel post. Most of the time, the shipping cost we are charged is more than the freight we are charging.
We also have a free shipping offer above a certain order value. We package every chocolate order into our custom made silver foil lined thermal boxes which is included in the shipping cost.
We tested these against Polystyrene boxes and they were almost as effective as polystyrene (polystyrene held the cold approximately 30 minutes longer) but much better for the environment and much better to ship in. Additionally, we use bubble inside the box to wrap the contents for extra protection.
