American Girl For American Girls All Over The World
My Costco had these too! You beat me to the post. :-DI figured it out; it is very reasonable pack. With 7 items - 6 books and the doll - 5.13 per item. Since mini dolls themselves are $22 (or more)...or when you think the books separately are 6.95 (now 7.95) each...you get 1 book and the doll for free.
I think stores realized that if American Girl will ship them stuff then they can sell them for cheaper and people will buy them.
