This is a simple site with many books. Each month a credit comes, generally for the full value of an audiobook, and I buy one with it. I can easily download the book to my Mac and either play it from the computer or transfer it to other devices. No problems.I have been using Downpour for my audio books for several years. I have been very pleased with them. Once a purchase has been made, the downloading process is quick and accurate. Only once did I run into a problem with a download. I contacted Downpour, and they fixed the problem immediately.
