A continuing problem for booksellers, especially those with an online presence,    is the receipt of fraudulent orders. A number of booksellers have reported receiving    bogus orders from overseas -- via either their retail Web sites or e-mail --    for large numbers of hardcover books, often Bibles or medical texts. These orders    usually originate in Nigeria, Ghana, Singapore, or Egypt and are usually in    excess of $150. The books being ordered are most often Bibles, other religious    titles, medical texts, or other reference books.
