Just a heads-up - Mark over at CLANG Armoury has a number of decent books up for sale on his site right now. Some are oft-sought titles, and at prices I could make a decent profit on if I snagged and resold them... but I won't be greedy here. He's offering 10% off right now to boot... actually, anything that is instock is 10% off. I don't know how long the sale is going on, and he didn't mention it on his site, just posted it on Armour Archive.

Usual disclaimer - I have no affiliation with them, just passing on an opportunity I saw.

I've bought from this guy a couple of times before with no problems. Some of his books are really fantastic deals, some are rare titles that can be had for less elsewhere. Always check prices on Amazon.com and Bookfinder.com first to make sure you're getting the best deal. :)
