Warlord Games is running a special where you can get all of the rulebooks for all of their games for one low price.
From the announcement:
We have a rather special offer for you – the Warlord Games Rules Collection!
All four of these glorious, full-colour rulebooks are included in this offer – an offer that saves you a not inconsiderable sum of money!
And you’ll not pay a penny in postage if you take advantage of this great offer during August thanks to our free international shipping offer!
