Brendan stand's by his guarantee that states if you don't think this is one of the best books of its type you have EVER read - return it to him at the address listed on the Contacts page of brendannichols.com and he will refund you double your money back. You must return a receipt of sale along with the book.This offer is only available through this page, NOT other booksellers. Obviously, this ‘double your money back guarantee’ is valid for one person, one book and one shipping address. You cannot order multiple copies, or order with different names, then return them and expect your refund. That’s only fair. As stated, your refund just covers the cost of the book, not your return shipping. Your guarantee is valid 6 months from purchase. You can keep the bonus video course valued at $495!
