1. This pillow sells at an exclusive store for about US$100. It is very expensive even in dollar terms. In order to save money, I bought it online. Also, by using accumulated points, I paid only about one third of the original price, with free shipping.
2. When I was getting the watch battery replace, the watch mechanic told me: "Wow, an Astro watch!"
He helped me fix some minor problems with the watch and refused to accept my payment. I am very grateful to him. I believe that people who like Astro are selfless people. That's a truly great spirit. I'm happy to find around me so people who are ready to help others.
