Donations to favorite charities, especially local charities is always a plus. Gift cards to favorite restaurants, movie theater, hair salons, stores, wherever they frequent - even grocery stores. We are in the same boat; at our age we have everything we need so our kids give us gift certificates for birthdays, anniversary, holidays, etc. They even gave my DH gift certificates for car washes. You could even make little gift bags to put them in and then they could re-gift the bags. Hope this helps.
