Kinda of confused at the ??? but I tend to be a little ditzy!!
Anyway, I think you are asking if you can stack percentages with $ off. When I went to my HD in Newark, DE, I tried to use 10% off plus $15/$125 and the cashier asked her manager and she said no

, so now I am stuck with a $15/$125 that I will probably not use UNLESS my hubby decides to get some stuff done around the house....Ok, Ok, I am....
Hope that helps!!
