If I was you, I would alter the "Tell A Friend" sidebox, so that it always appears. If it is on a product page, then show the Tell a Friend about the product, and if not, tell them about the store. This can be changed in includes/modules/sideboxes/tell_a_friend.php .

Next you will need to change the sending email script, which is found in includes/modules/pages/tell_a_friend/header.php

Here I would check if you have a product_id sent in, which is detected in line 19 of a zen 1.3. If not, by adding and else to line 34, then set the email up to send the Our Store email.

As for cc-ing yourself in, you can send yourself a copy of the email, by re-running the send email line of code.

Hope this gices you some ideas.
