Combined shipping is a way for you to save money on shipping costs!! When you order more than one Cup of Grow fertilizer product, you will have the option to have the total solution shipped in a fewer amount of boxes. DON'T WORRY, you are still receiving everything that you paid for, but I am storing the contents in fewer boxes to decrease your shipping cost.
You still have the option to purchase Cup of Grow using regular shipping prices in which case you will receive all the boxes! If you have any other questions, feel free to email me and I will help you out as soon as possible!
