A good place to buy inspirational thank-you cards is Compendium's online store at Live-Inspired.com. Compendium also sells its inspirational thank-you cards in thousands of different specialty gift stores throughout the United States.
Compendium's line of inspirational thank-you cards is called Positively Green. They are green because they are printed on recycled paper with soy ink, making them environmentally friendly. Each Positively Green thank-you card is beautifully illustrated and features an inspirational quote, along with the words "Thank you." One card features a quote from Thornton Wilder: "The happiness of life is made up of little things. Every little thing you do makes a difference."
