Home Depot has DEF 2.5 gal for $12.00
I was walking down the aisle and saw they are stocking some auto supplies now - oil, wax, wipers, batteries, etc.
I saw they had DEF for $11.97 which is better than Pep Boys and others that carry the same for $15.00. I don't have any real truck stops around me otherwise I would fill up cheap with the big boys but at least I saved a few bucks so just an FYI if you want some at a cheaper price than the car places.
