I have a Drupal 6 restaurant site that I am updating the appearance, not the version -- and the client would like to add promotional coupons to their site or to an email distribution. These coupons would allow the customer to come into their restaurant and receive a discount on something -- maybe a birthday coupon or something like that.
Do you know of any drupal module or service or 3rd party, etc. that will restrict the printing of their coupon to only one time and allow them to track the coupon?

The uc_coupon module allows
The uc_coupon module allows redemption limits, both total per coupon and per user.
Tie the Coupon to a user account
One thing that might be interesting is to use the coupon to require them to create an account. Then the coupon would be unique to their user ID, and could be checked against the website. Just let the user setup their account, and you have them for later promotions too.
