I also love the Economist audio edition. I listen to it during my commute, and mostly get through it each week. It kept me sane on a horrible commute with my previous job.
They have a separate digital subscription, if you just want the website and audio edition. It is included in a print subscription as well. You can buy a single week, if you want to try it out.
Highly recommended if you want to ignore the advice of the OP.
Sorry, it changed since I last looked. They used to offer a regular subscription with both digital and print, or a cheaper digital only. As you say, now they offer the regular option with both, or a cheaper option with either digital or print.
