I am interested in buying some or all of the Osprey Men-At-Arms series on the Wehrmacht and Waffen SS. I believe there are 5 of them for the Wehrmacht and 4 for the SS. I can find most of them on Amazon.com for pretty reasonable prices ($3-$8 new or like new), but the shipping costs ($4 per book) are fixed and can't be combined even when purchased from the same re-seller (other than buying them at Amazon's inflated prices).

So I'm curious if someone wants to unload theirs at a reasonable price and at reasonable shipping costs (I'm not in a rush, so Media Mail is fine).
