Just received a letter from National Geographic with a welcome back offer:
1 year membership at our lowest rate £15
PRINT: 12 monthly issues of the National Geographic magazine
DIGITAL: A full year of the magazine with exclusive content
2 FREE gifts: fleece jacket and jumbo world map
FREE Access to Nat Geo PLUS
Worth trying to re-subscribe not sure if this offer will be available to everyone but I gave them a call on 0345 0450355 and was asked the code on the letter I received NFCQJN0 which I think it's not personal,will work on any account.
As I found the Nat Geo offer on HotUKDeals when I first subscribed if I can help a fellow hotukdealer than its great.
Not sure how new members can access this offer, worth trying giving them a call and quote this voucher code
