Custom Magento Extension for Multiple Coupon Codes for distinct Promotions

Designed and implemented a unique custom Magento extension that allows for generating multiple coupon codes for a specific promotion. The admin can duplicate an existing rule or a coupon to create several unique coupons that can be then distributed and used by website users. We also implemented creation of coupon codes from a csv file upload containing codes. Checks and rules were implemented for duplicate coupon code detection and replacement of such values with new unique codes. Other features we implemented was pattern definition of the coupon with length checks. The extension helps users create coupons for any price rule.
