This is not an incredibly cheap deal, but you need to remember that you can’t buy Miles & More miles. If you want to top up your account, you are reliant on a transfer from a hotel programme.
Here’s the offer:
For €586, you can buy a digital subscription to Germany newspaper Frankfurter Allgemeine Zeitung. The link is here. This comes with 40,000 Miles & More miles.
You are paying 1.25p per mile. This is not cheap but if you have a firm plan for the miles it might make sense.
