Book Depository carries both Minder and Adversary, and I sometimes use it to send giveaway copies outside the U.S. They pay me royalties and have free shipping, so it's actually more cost effective than sending an in-stock copy from New Hampshire.
They also have a "watch people buy books" feature that I find hypnotic. Check it out here: http://www.bookdepository.co.uk/live. It's like watching fish in a fishtank...if the fish were buying books.
BTW, if you're still in the market for a query critique, J.N. Duncan's giving one away from none other than Nathan Bransford! Check it out here.
