The first page of the ebook claims a free audiobook is included, I followed the necessary steps exactly and no audiobook. Tried again, no go. I then contacted Bigger Pockets support who seemed very helpful at first, asking for the email to my account to verify. Since then I've emailed them multiple times for an answer even including my order number without so much as a reply back.
The audiobook isn't expensive but the fact that it's offered for free at the start of the ebook and there is no way to get it is ridiculous. If the offer is no longer available I'd expect them to update the ebook.
