Do you only offer e-book formats, or do you offer pdf too ?
Is there any chance you offer audio books too ?
Hi, this promo is finished already (all 5 books served).
Yes, I do offer both ebooks and pdfs for $1 btc each. Some audio books are available too for $3 btc per audiobook.
Please check out my regular thread for details or send me a PM:
