Is this the total cost for all the boards and everything for this deck?

Hello. Thank you for reaching out with your great question. We would reccomend reaching out to the specific Lowes store you are looking to purchase from for exact pricing. They would be able to provide you with a quote regarding all material that would be needed for your project. Each store sets their own pricing according the the local market.
