You have to go online to homedepot.com and register for an account to get the discount...I would think that somebody in the store would be able to help you out if you do not have full internet access because not everybody has that... Once you register you get 10% off of eligible purchases every day according to their website
Online are call the main office
They do have a military discount, but I would go inside and speak with someone who can better help you
