Used books!
I've got 82 titles for sale. Browse the list, there's a wide variety. Make me an offer in BTC.
Be sure to click the USD price to see the copy I have for sale and the condition notes. Also please note that shipping is not included in the listed prices. However, I can weigh any book and tell you the shipping price right away. For BTC buyers, all shipping options are available, and I will ship anywhere in the world.
PM me via this forum to make an offer and reserve a book. From there we can switch to any communication mode you like.
