You may have had the opportunity to try the Findmypast site at the BIFHSGO conference; perhaps you won one of the door prizes they offered or took advantage of the 50 free credits available to all attendees.
Now there's a 50% off offer - that gets my attention - available from findmypast.co.uk until the end of September.
Get your 12 month Britain subscription today for just £49.75 (usually £99.50). Your discount will be applied automatically, but should you have any trouble, simply type the code SEPT50 into the promotional code box at the bottom of the payment page and click 'apply'.I'm a long time findmypast subscriber, now through the .com site. Their unique resources, especially the digitized British newspapers, keep me renewing. And in case you wonder, I get no kickback from publicizing this offer.
By the way, Findmymypast and findmypast are used interchangeably on the company websites.
