Interested in buying the Tsukihime Remake? Visit the purchase page and find out where you can find Tsukihime.
The original Tsukihime and Kagetsu Tohya are abandonware, so there is no way to acquire it through TYPE-MOON themselves. Don't feel bad about not giving scalpers your money just to read this VN. If you want to support Tsukihime, purchase the Remake. When reading, I heavily suggest using this guide.
