I just had this mystery coupon arrive on my test account via my test site. I am in the process of installing the IntergratedCOWOA(1.3.8) module. When I was going through the steps to see if the module was working apparently it makes an account for the customer somewhere between step 1 and step 4. Anyway, the welcome email said:
Your Discount Coupon - As a thank you for joining our community, we've included a 10% discount coupon. You may use this coupon once to get 10% off any order, large or small. It is good through December of 2007. The coupon code is '08825bbc50'. To use this code, enter it during checkout in the coupon entry field.
Well I did a search of all the files installed with this module and in the /includes/language/english/YOURTEMPLATE/no_account.php file on line 39 it says this:
define('EMAIL_TEXT', 'With your account, you can now take part in the <strong>various services</strong> we have to offer you. Some of these services include:' . "\n\n" . '<li><strong>Permanent Cart</strong> - Any products added to your online cart remain there until you remove them, or check them out.' . "\n\n" . '<li><strong>Address Book</strong> - We can deliver your products to another address other than your own. This is perfect to send birthday gifts directly to the birthday-person themselves.' . "\n\n" . '<li><strong>Order History</strong> - View your history of purchases that you have made with us.' . "\n\n" . '<li><strong>Products Reviews</strong> - Share your opinions on products with our other customers.' . "\n\n" . 'Your Discount Coupon - As a thank you for joining our community, we\'ve included a 10% discount coupon. You may use this coupon once to get 10% off any order, large or small. It is good through December of 2007. The coupon code is \'08825bbc50\'. To use this code, enter it during checkout in the coupon entry field.' . "\n\n");
I would suggest doing a search of all the files of the modules you have added. I use Dreamweaver to do my search. Dreamweaver will search within the source code of every file in a specified directory.
I hope this information helps somebody.
