I recently purchased 60,000 Miles-and-More points through the Melia Hotels 25% bonus offer; came to $1000. That was about 1.67c per point. I know buying points is anathema to many around here, but for me, this is a very good value as I'll use these points to book Lufthansa or Swiss Int First class, which is a very expensive product. I'm happy to rack up the free points, but also don't mind adding to the balance with some value purchases.

This has me wondering, aside from the targeted US buy right now, are there other below 2c/pt methods for buying, maybe through other hotel loyalty programs?

While I'm at it, does anyone else find value in purchasing points like this?
