Case Studies Wanted for New Book

I'm currently working on my new book 'The Loyalty Gap' which is being published in October. The book features several case studies of businesses that have been successful in nurturing highly loyal customers, and it will examine the strategies that the company used to keep their customers loyal.
I'm looking for a few more businesses to feature in the book. If you'd like your own company to be featured please contact me by clicking here.
You don't need to write anything, but I would need to interview you, either on the telephone or by email.
If your case study is used in the book, you will receive a free signed copy and an invitation to the launch event in October.
