Until the end of January deceasedonline.com is offering buy one, get one free on their vouchers. Here's the notice I received (if you're not presently a subscriber it's easy to register.)
"As a subscriber to our bulletins, Deceased Online is delighted to offer you, until 31st January, the opportunity to double up on pay-per-view vouchers* used to access records and data on www.deceasedonline.com. *Excludes subscriptions
The 'buy one get one free' offer means that all purchases, which start from only £5.00, will provide double the number of vouchers paid for.
When purchasing vouchers simply click on 'add a promotion code' and enter the special code DOL2015 in the box provided. The number of vouchers purchased will be doubled automatically. View our normal pricing schedule here.
With millions of records added in 2014 and with millions more coming soon in 2015, users will be able to access a wide range of data but at half the usual cost."
