Discount Code Generator
Allows site admins to generate discount codes in bulk and them export them directly to CSV. You can generate an unlimited number of discount codes and control the exact options for the discount codes that are generated, including required products, minimum amounts, one time use, etc, just like standard discounts in Easy Digital Downloads.
After discounts are generated, they can be immediately exported to a .CSV file.
If you need to import discounts in bulk, look at the CSV Coupon Importer extension.
