Absolutely! Our payment processor is one of the largest in the country, uses 128-bit or higher encryption, and is tested daily by McAfee and VeriSign. And you can also use PayPal if you like. Either way, your payment will be about as secure as they come.
We offer a 30-day trial period which means that you have 30-days to decide if the book really is what you thought it would be. If you feel it's not up to par, then simply send us an e-mail with your purchase info and we'll issue the refund. All that we ask is that you provide a bit of feedback so we can improve it for other landlords.
Unfortunately (or fortunately depending on how look at it), I am not a lawyer and cannot offer you legal advice. If you feel you need additional advice for your unique situation, send me an e-mail at John@EvictYourTenantNC.com, and I'll refer you to an attorney who can help you out.
