03192008 -- OsCommerce Coupons -- $30

I have a LIVE site right now that has the coupon code system installed, but appears to not have been installed correctly. Need someone to go in and clean it up, or uninstall and install another, I have no preference. Just need to be able to create coupon codes and codes must be able to be redeemed. Need this done right away. Only other requirement is that if you're putting in your own coupon module, there must be an option to create a Free Shipping coupon. That's it! $30 bids only! Thanks, T
