I was surprised to learn recently that Lowe's offers a 10% discount on all purchases for military service veterans. Even talked to an individual who said when he found out he took old receipts down and they made refunds on those purchases (this I would have to see).
Just need to show them your DD214 form and all is well.
(I have no affiliation with Lowe's and don't even like to shop there, but this makes it more inviting.)
