Chris,
I tried (and was somewhat successful) purchasing some PDFs last week (Thursday or Friday). I had several problems and emailed Morrus per the "Contact Morrus" at the bottom of the webpage. He has not replied.
One; using a credit card kept giving me errors, I contacted my CC company and they told that there was a duplicate charge, which they deleted.
Two; on Saturday the PDF links finally showed up on my account page, but one of the paid for PDF link is not working
Three; none of the free stuff I selected is included in the list of links to d/l, I included the free and paid for PDF in my basket together
Four; I never got a confirmation email with my purchases, so I don't know the PO# or invoice#
Who do I contact for help?
