One of Arizona's favorite spots to shop for super deals is expanding. On March 14, Arizona Mills in Tempe will debut an expanded H&M store, adding children’s fashions. Come summer, Arizona Mills' first-in-market locations of O’Neill and Conn’s will open at the mall while Shoe Palace makes its debut at the shopping center very soon. O'Neill is a leader in beach lifestyle sportswear for men and women; Conn's will sell everything from appliances, electronics and computers to furniture, mattresses and lawn and garden equipment; and Shoe Palace specializes in athletic shoes and apparel for the whole family. www.arizonamills.com.
