Got it working
Thanks for your direction with this - I now have it working. I can see how I can modify the email and adding an Email-friendly cart nicely places the CSS inline for email delivery - thanks for thinking of that.
The one problem I'm now having is that it's sending out two emails to everyone - the customer and the BCC field where I placed the store owner's email. I've looked at the code and am not seeing any of those entries duplicated. Any idea what's causing that?
