Ernie G,
There are a couple of major-ish problems at
http://www.greg-gregory.com/
Including:
No example license on the site.
Forcing non-US customers to enter a US state in the shopping cart.
No delivery instructions or info prior to going to the shopping cart.
Finally.... a non-SECURE Credit Card page.. which made me finally give up and not buy anything..
Yet another content provider that is unusable...
