I dread taking the wife to HD too, she hits up the cleaning aisle... for stuff she already has .
When I mentioned that I was lost, I am used to the HD 5 minutes from my house. I know where 90% of the stuff should be. Bad to the point that an employee has asked me where something was at (of course, I knew).
I don't think she understands cost per square foot v. cost per linear foot v. cost per piece.
I tried to explain and quit.
