There is a demo of ProofBuddy available at http://demo.proofbuddy.com.
To login to the demo you can use either white_glass or basic_white to see the two different available themes. More themes may become available on the demo as they are created.
Note that the shopping cart has been disabled for the demo. Normally each image would have a form to add items to the cart.

I’m interested in using Proof Buddy, but I have no idea how this works…my clients look through their proofs, pick out what they’d like printed, and pay via PayPal. Then what happens? Please walk me through the process, step-by-step so I can understand it.
Thank you!
