I have put online the first implementation of accepting bitcoins for oan inventory of thousands of used and out of print books.
We are using mybitcoin for now to accept payments for books:www.pleasantstbooks.com
If anybody is interested, please take a look let me know if this is a reasonable way to do business, or if this is too basic an implementation for anyone to use. Or, pick up some books from your mining profits. The books are also listed on the American Book Exchange, and through there on Amazon.
Cheers and happy bitcoining -
