I'm looking to match patterns or simply allow wildcards in coupon codes. For example, if I'm offering a discount to a member of a club and I know the membership numbers match a pattern, I would like to allow it as a valid code.
I tried * in the codes but they are not accepted as valid characters.
Alternatively, I could parse out all the member numbers and import them into the discount code field but there would be hundreds of them. Is there a limit to the number of codes? Will a lot of codes slow down the system?
