It seems a bit hard to say. Probably each week, that is about once a week. Specifically, on holidays or public vacations. People tend to do it in this way quite often in life. For one thing, shopping is a proper way to release bad emotions in life, after shopping, lots of people might feel extremely happy, it is kind of like psychological demand or pursuit. I think that most of us would understand why. For another, shopping is a necessary part of our everyday life. We have to do it mainly because it is a part of our life. That is the point. Like going to the supermarket to grab something you like or need for example. So, I think most of us tend to go shopping each week at least. That is it.
