When you buy one of these audiobooks, you will receive an e-mail from Spartamac with a download link. Please note, that you will be downloading a .ZIP file which contains the audio. You cannot play the .ZIP file directly. It needs to be decompressed. On most PCs and Macs, all you need to do is double-click and a folder will appear that then contains the .MP3 audiobook files that can be played in any modern audio player or on your phone. If you have any issues, please do not hesitate to contact me, and happy listening!
