Lufthansa’s Miles&More program sells miles in an unusual way, bundling them together even though the other components don’t make much sense.

You can purchase up to 250,000 miles in a calendar year using bundles, excluding the bonus. The November offer is valid through the end of the month, is open to members who haven’t purchased their miles previously, and includes up to a 50% bonus.
You can access this offer on the Miles&More website here (EUR), here (GBP), or here (USD).

Conclusion
Whether buying Miles&More miles makes sense depends on how you use them. The move to the dynamic awards was not as bad as many feared, and there have been few deals to be had.
Required mileage amounts vary significantly, and the price (in miles) is usually higher at Lufthansa Group hubs, as with revenue fares.
There have been previous sales with up to a 60% bonus, as was the case in May, and who knows, perhaps there is a similar Black Friday/Cyber Sale later this month.
