CW offers 2 subscription options - digital or paper. But the digital option also gets you the monthly special edition in the mail.
I get 52 issues and the digital every year. The digital is good for when I'm on the road. The paper is for when I want to kick back and get comfortable.
The digital edition comes free with the paper subscription. I rec'd the paper sub for many years but last time around I switched to the digital, which I find very handy despite a couple of bugs that CW has been notified of but hasn't yet fixed.
I prefer the digital because it makes it easier to take around on my iPad. I have the Numismatist, Coinage, & World Coin News among other subscriptions. I also have the Red Book 2012 ebook on my iPad. One device to take all those magazines & books!! Makes it so convenient
