I buy my CA subscription w/ "airline miles" because it keeps my account active once a year so I don't lose the 18,000 miles I have earned(if you don't do one transaction every 16 months they can cancel your miles/US AIR).
Since I have no $ for travel, I won't keep the acct. active by flying or hotel stays because I'm not traveling.
CA is THE LOWEST mileage cost of any of the 30-40 magazines they offer. It is only 400 miles for a years subscription.
Hence I kill two birds w/ one stone.
It does get depressing reading about watches that cost three times what I used to make in a year.
They do have some good articles though.
I recently did the Christmas gift deal where you got two subs."BOGO"(for my some friends of mine) for one year at $19.95, which was a deal.
