I see the calendar of my grandmother gifted that has let him buy even extra on Amazon. The calendar is also really smart and makes NEN appealing impression, I am fully happy until the hammer came. For your own device (Kindle Fire HD) because there are no app So, I called and learned that there probably is no app at the customer service. I realize that Milka decides who gets the app and who is not, but Amazon as a distributor could also say: So we do not sell that thing up! Now I'm looking though the chocolate, but you could have bought also NEN cheaper calendar by far. Poor performance, Amazon!
