The Nancy Drew folks released two newsletters during December. I've been talking about my trip to Spain over the past week and a half, so I haven't had time to talk about them until now.
The first newsletter is about their holiday sale. Buy a physical copy of one of their games, and you'll get it for half off! You also get a free strategy guide and a Koko Kringles chocolate bar. The sale is still ongoing, but they've run out of chocolate bars. Sounds like the sale was a success.
The second newsletter is about their second text challenge. From what I can tell, it's basically a series of puzzles, and you have to text your answers to them. Get enough answers right, and you could win the big prize! If you don't get enough answers right, you're still in the running, but for a lesser prize.
