Price Club one of a series of enormous warehouse stores. These cavernous stores are stripped of amenities such as dressing rooms, music, fancy displays, and a multitude of salespeople. Sometimes one must belong to a union or other large organization to be a member. There is also a yearly membership fee. Since the stores are so stripped down, their prices tend to be far less than department stores. Like the "twice-used Macy's bag," Tan mentions the store to let the reader know that the mother is very concerned with getting her money's worth. Unlike the daughter, the mother is very thrifty.
