This is a really good deal, for those who want to try out Findmypast. They’re offering a 50% off flash sale on their monthly world subscription. So for US$9.98 you can check out their worldwide collections, including the 1939 Register.
Just be aware that 1) the sale ends at midnight this Sunday and 2) your subscription will auto-renew at the regular monthly rate if you don’t turn off that option in your account settings.
