Present For Mother`s 2nd Marriage

My mother is remarrying on April 30th. I myself am getting married on June 26th. My fiance and I are paying for our wedding ourselves so money is rather tight. Does anyone have any ideas for a wedding present I can get my mother and her intended without breaking my bank? They`ve bought a house together and have furnishings, decorations, etc. So those ideas are out. Thank you for your help!
