New (very happy) user of eStore and PDF Stamper here, right now sandbox testing with Paypal and am running into the same issue as the original poster of this thread. Everything worked fine when the user had to manually return to my site from Paypal after the purchase, but now that I have PDT working the PDF files are stamped with just:
"Licensed to Test User of , , , . Email address: brent_1295058388_per@deshazer.net"
Before this they looked like this:
"Licensed to Test User of 1 Main St, San Jose, CA 95131, United States. Email address: brent_1295058388_per@deshazer.net"
The $0.001 shipping amount trick did not work for me either.
Not too worried about the phone number but it would be nice to have the address in there...
