Mindful Market encourages all of our users to sell internationally for a few reasons. By including the option of shipping Internationally, you are opening yourself to a much larger customer base. Most shops that have embraced international orders see an increase in sales.
The way the Mindful Market marketplace is currently setup we do not have a way to block international customers from seeing shops that do not want to ship internationally.
Be sure to communicate in your shipping policies your desires to ship, or not ship internationally.
