The National Geographic Store offers The Complete National Geographic for Windows and Mac for $24. With $5.95 for shipping, that’s $5 under our July mention and the lowest total price we could find, this time by $30. (It’s also less than the lowest total price we’ve seen for the 2009 version.) This is a complete digital collection of every National Geographic issue from 1888 through 2010 on six DVD-ROMs.
