The list price on the site is $23.88 per year, but you can use code “SAVE5SMNOW” to get a year for just $18.88.
This is the lowest price I’ve seen this magazine offered for in a long while. I think it sells rather well so doesn’t really need to go on sale like some of the other magazines out there. The discount is valid through March 5, 2013.
For comparison’s sake, a one-year subscription from Amazon is currently $23.88 per year.
