free customizable postcard sent to anyone, anywhere in the world. Get started here. You can use one of their Olympic images or upload your own image, add a message, address, and they will pay for the postcard itself and the postage. You can enter multiple addresses and send additional free postcards. Be aware that your created postcard (with just first names) will be posted to their postcard wall.
Joshua and I are thinking about sending one every day from our upcoming vacation. Great freebie!
