I am planning to play some more Song of Blades and Heroes with my kids soon, so I thought I'd get a couple of supplements. I bought the PDF's of Song of Gold & Darkness and Song of Wind & Water. Since I needed to print out copies I had the idea to make one big rule book.
Staples has a Printing Service (Link: HERE) that is very reasonably priced. You can email them your documents and pick up the printed rule book in a day or so. I didn't know if they could combine the different PDF's but it turns out they can.
So I had SBH/SGD/SWW printed in that order in one book along with a color cover for $13. I think that is a good deal. I got the the coil binding which I think works best for wargames rules.
I should have bought Song of Arthur and Merlin as well, but I forgot. But the 3 I have are more than enough for my kids and I. Here are some pics of the printed book.
