oscommerce addons (for Ralph)

I need 3 contributions added to a custom oscommerce site. The design has been customized so special care will need to be taken when installing the contributions. The contributions are.. Easy Coupons Get 1 Free Purchase Without Account I also need the thumbnail image optimization for the cart images fixed. It's over-optimizing and making the images blocky (for lack of a better term) This job will go to Ralph cuz Ralph rocks! Thanks!
