How can the packs be sold at this low price when one individual board is so expensive?

Hello, and thank you for your interest in Trex! If you are seeing a low price it is most likely showing the individual board price which may need multiplied by the full bundle quantity of 64 to obtain total cost. For further pricing questions please contact your local Lowes store at the lumber desk for assistance. I hope this helps get you started in the right direction. Thanks, Tori - Trex Customer Care Team
