I ordered this for my niece. She absolutely loves unicorns and rainbows. I had wanted her to be able to enjoy the entire story so I went to the website to add the previous book inserts. Since I started the subscription for the fifth box. They had the first three book inserts available for purchase but the forth wasn't listed. I email asking how I could get the forth one. I have never been so incredibly surprised by a customer service team such as this. They responded almost immediately, like within minutes. They explained that the site had not been updated yet and they would include the 4th insert for free. Honestly I never expected that. I could have cried. Because I don't get to see my niece since they live across the country now and I wanted her to have the opportunity to enjoy the entire story. This box is my way of letting her know how much I love her and I'm always thinking of her. This company, their products, and their customer service are absolutely the best with everything they do and offer. I can't thank you enough for all your help!!
