Because discount codes may have been sent out, discount codes cannot be altered or changed once they’re created. The proper way to modify an existing discount code is to simply disable the old code and create a new one. Note that the exact same code cannot be used more than once per account. For this reason, if you’re creating a discount code for a specific yearly event, we recommend adding the appropriate year suffix to ensure uniqueness of the code itself.
Example: Instead of “SUMMER”, use “SUMMER2017”
