    delivery of e-book (using paypal)

    Hello-

    I'm selling an e-book online and will be using Pay-Pal to process the transaction.

    The question is: What is a good method for delvering the e-book to the customer once payment has been received? I know that Pay-Pal allows you to specify a .htm page to redirect to once payment has been made, but I want to make sure it is secure and that the person could NOT just simply copy+paste the url and share with their friends.

    Maybe a PHP script or something that emails them the e-book???

    you may want to check out some of the digital goods solutions listed here:
    http://www.paypal.com/cgi-bin/webscr...-goods-outside

    most charge for the purchase of their software, nothing thereafter. others like www.payloadz.com are hosted services and may charge per txn.

    thanks for the reply. i think, after some research, that payloads.com is the way to go.

    thanks again.

    I sell eBooks in PDF format and it's a fact that, no matter what you do, you can't stop people from emailing the download URL or the eBook file to a friend. What's the answer?

    Let them get on with it. For every dishonest person there's 99 honest ones.

    I combat it in three ways:

    1. A "Conscience" note in the eBook saying "if you got this through eBay, Kazaa, Limewire/Gnutella or from a friend then you haven't paid the author and it's an illegal copy. Please go to xxxx and pay for your own copy. You'll feel a lot better.... etc.

    2. Flood Kazaa, Gnutella etc. with dummy versions of the eBooks so the chances of someone finding a real copy are much lower. After downloading several large files that turn out to be simply 60 page adverts for my books, they tend to give up!

    3. "Hide" dummy eBooks in a "secret" directory on my web site where people will find them.

    4. If I find a legit copy of my book on any web site, I write to the ISP asking for the directors' names and addresses for possible prosecution, followed by the URL and details of the copyright material. This always results in a closure of the URL and they may or may not ask questions later. Basically ALL ISPs will play safe.

    BTW I would definitely not offer to deliver eBooks by email. Downloading is much quicker because this uses straight binary. Emailing requires a conversion to ASCII which, even after "compression" is going to result in a large file. Apart from that, and the fact that your compression method may not be compatible with their computer, sending email attachments is just bad news. Many people will accidentally "bounce" them or filter them out as spam. After all, how do they distinguish your eBook file from a possible virus? You'll get endless complaints "my eBook didn't arrive". Also, ca you atomate sending the correct eBook by email? It's much easier simply to give a download URL in the "thanks for your payment" message. If you are feeling paranoid, you can change the URL from time to time.

    Martin-

    Thanks. All great tips! I'm going with PayPal/PayLoadz which will send the buyer a link to download the zipped up e-book after payment. Seems to work just fine for now.

    Erm, if it's a single PDF file, you don't need to zip it. That will not make it smaller.

    In fact, if a Mac User buys it he won't thank you for using WinZip!

    You could also use OScommerce, just mod it to only work with your one book, but will also give you the opportunity to add more books in the future.
    You can also capture more details from your customers, plus it has a lot features for download products. For one you have to be logged in, and you can restrict the number of downloads, they do not visit a direct download page they get presented with a link which expires. Whats more its free and can be used with the paypal ipn.

    If you need any help putting it together, I can help you out no problem

    There are lots of options available...

    - Most Ebook software offer various options to encrypt the file...the "HDD serial number" option is excellent to stop people from spreading it around.

    - Adobe Acrobat also allows you to encrypt the file

    - Most exe. or zip programs also allow you to encrypt it

    If a normal password is used just change it at regular intervals...but username + serial numbers work great and not many people will spend the time to crack a E-Book.

    But have a look how software programs are currently downloaded, there lots of free options available. Just apply one to your e-book!

    Check these out, but there are many options:
