I'm doing several freebies and I want to restrict the items to 1 per mailing address, IP and email address, but I don't necessarily want them to have to create an account. (Obviously I don't want to send all the items to one person, but they're freebies I want to make it as easy as possible.)

Does anyone know of a plug in or a setting within Zen cart that will do this?

I haven't built a Zen Cart in a year (almost to the day according to the login record.) I'm a little rusty. With the newer version things don't seem to be where I left them lol

Thank you.
