I read on another thread where someone talked about giving those energy saving light bulbs and installing them for an elderly relative. That way they could save on their bills, and they wont have to worry about falling while trying to reach a bulb,as they last for years.
I have given stationary, note cards, etc. My mom gives a calendar and paper clips $5 or $10 to each month so grandma and grandpa can go get some coffee or a doughnut as they are on a very limited income.
I have seen picture frames somewhere online that you connect to a phone line, pay a minimal monthly fee, and you (or anyone) can send pictures to the photo frame, so that you can show off your new photos without mailing them, new ones just 'appear' in the frame.
