I'm a newbie to Zen Cart and this is my first post. So far Zen Cart has been pretty easy to setup. Almost everything I've tried setting up I've been able to figure out. I'm stuck and cannot figure out how to setup a product for sale that is digital but I don't want to have a download option or a shipping option. I would like to sell the software which is custom created for each order and I want to send an email to the buyer with a link to download thier software once I have the software ready.

How do I setup the product with no download or shipping offer with a note that the software will be ready for download within 24 hours?

I'm using version 1.5, no upgrades, no addons.

Thank you for your help.
