It depends on what kind of business you have and if the jars are full or not. Shipping costs are based on package weight and distance. Empty glass jars heading to the next county will be much cheaper to ship than full glass jars heading to the other side of your state. If you’re a cannabis packaging and distribution center, you’ll want to factor in the cost of shipping to your budget. You’ll also need to use plenty of packing material to ensure your jars don’t break en route. In general, the USPS is the most affordable (albeit slow sometimes) shipping option.
