Subscription to spam National Geographic used to be a very respected journal. Now, they teamed up with Lindblad Expeditions. Once you subscribe to National Geographic, they sell your address to Lindblad Expeditions without asking for your permission, and you start getting catalogues of offensively expensive travel offers, tens of thousands of dollars per trip, from Lindblad Expeditions, and it is impossible to stop. Cancelled National Geographic because of Lindblad Expeditions spam. Called National Geographic for help to stop the spam. Looks like the spammers may be their partners. The frequency of spam got less but did not stop. Please, save your sanity and DO NOT SUBSCRIBE TO NATIONAL GEOGRAPHIC!!!

For a magazine of such standing National Geographic Digital … For a magazine of such standing, I am sorry to say that their digital version service is atrocious ! I have a paid membership which does not allow me to read any articles which are emailed to me on a daily basis. I have tried every single path, to read the articles, to no avail. A total waste of money!!

Good work NG! Difficulties with getting our magazines at our foreign address led to our becoming acquainted with Jodie. She has done a smashing job of seeing that things were set right. Cannot say enough about the wonderful, caring, attentive service we've been given as the details were ironed out. Good work National Geographic!!!
