The MAC consultants at Dillard's in Omaha at Oakview mall tells their customers if you bring in your empty foundation bottles you get a free one. First they tell you that you need four. When you bring in four they tell you " no, it's five". Then, when you bring in five, they say "no, it's six". They keep adding one every time so you never get the free one they promised! Isn't this illegal?
