You can test out how the PDF stamper works from this page by making a test purchase using the simple PayPal “BUY” button below. Please only test it if you are serious about this product (we will not give a refund for this $1 purchase).
The Whole Process includes:
- Making a test transaction by clicking on the “Buy Now” button (The test product is $1)
- After you make the payment the plugin will stamp a copy of the PDF eBook with your details (e.g. Name, Email, Address)
- Finally, the plugin will send the stamped PDF file to you via email.
How does this work with a subscription? I would like to send out my ebooks monthly to my customers. I wouldn’t want them to always have to click the Buy Now button.
Please advice. Thanks!
@MD, It works with any type of button “Add to cart”, “Buy Now” or “Subscription”. My question to you is.. are you planning to send a different book every month? With every button you can specify the URL of a PDF file that will be sent when the payment hits your account so I am not sure how this whole sending a book every month is going to work.
Yes it would be a different ebook every month and the customer would only subscribe once. Would this still work?
What’s to keep somebody from deleting the footer section that contains their information?
@MD, The Plain PayPal button option won’t work for that.
You might be able to achieve something similar if used with the WP eStore plugin whereby you can change the URL of your eBook in the “Digital Content Details” section before the month ends so every time a recurring payment is charged, a new link gets created with newly stamped file and gets sent out to the customer.
@John, One of the many benefits of using PDF file format is that the end user cannot modify the content of the file. Remember, the purpose of this plugin is to add another level of protection to your eBook without causing customer annoyance (usually password protected PDF files annoy the customers. Besides, the customer can just share the password together with the eBook). This plugin alone is not going to give you 100% lockdown of your eBook. Just because someone in this world can pick my lock doesn’t mean I am not going to put a lock on my front door 🙂
Any plans in the future to make it work with a subscription button? Or for me to do it semi-automatically?
If there was a way to do this then I would do it. The problem is that subscription buttons are not meant to sell eBooks. How can you specify a different ebook (which is to be sent out each month) in your one subscription button?
It’s a fabulous idea. But with dripped membership courses, often a PDF file is made available for download at weekly or other intervals, while the client is billed separately on a monthly basis.
I see how it would be difficult to impossible to get different member info on the files. Linking the process into paypal is very clever.
I would definitely use this for separate e-book sales.
Lovely theme, BTW.
Maybe I’m missing something, but couldn’t you just incorporate the primary key for each user that would associate their address with all new links generated by your membership script? Instead of stamping the pdf on purchase, you simply run the stamper script at the same time you build the links for your dripfeed and store the pdf’s in the customers folder.
For instance, username: john123 has a subscription to your dripfeed and he receives a new link every week. His ID in the database is 52, so you set up a script that grabs his ID and builds the link to the stamped file in a unique folder. The reference to his ID #52 in the link will be associated his address on file and that can be passed to the stamper script so the pdf can get stamped and stored in his folder. Some obfuscation would be in order to mask your url so that users couldn’t reverse engineer it with another user’s ID, but it’s doable. You might also create a CRON job to empty the user’s file folder after a certain amount of time to prevent them from sharing its location.
