Just won a PHB on eBay for a mere 8 bucks. I've been trying to get all the nation and secret society books for HoA and at this point I'm about 3/4 of the way there. What's taking me so long you ask? Why my refusal to pay more than $5 for nations/SS books or $10 for PHB.
What's that you say? You can keep a lookout for me too? What do I have/need? Sure, here's the list...
Have
Castille, Eisen, Ussura, Vodacce
Explorer's Society, Invisible College, Los Vagos, Knights of the Rose and Cross
PHB
Need
Avalon, Montaigne, Vendel/Vesten
Remember the rules, no more than 5 bucks. I don't really need them that badly (having two personal copies of each myself)
