For only $10.99 (including shipping) this is a amazing deal! I have only receved my first letter June 23, 2017 and it was so amazing. It was to Sirius From James written to him the day before he dies. It was so sweet & amazing!!
This was my first letter,
" October 30, 1981
Harry is at it again, and when I tell you what he's doing, I'm sure it'll come as no surprise since you already know his father. Hopefully, you'll get this letter I sent it with wormtail.
Anyway he's been flying so much. He's so talented he can already weavve around all of the table legs and the couch. I swear we have a future Seaker on our hands, as much as I'd like him to be a chaser like me. I can't wait for him to go to Hogwarts, I just know that he will have so very much fun there, just like we did.
It's important to be thankful for the small moments. It appears that your idea with regards to the flidelius charm was a good one, I believe we're quite safe here.
All the best, James"
