When you join an eCommerce program that's offering a referred customer discount, Kickbooster generates a referral link AND a discount code you for you to share when promoting the store.

The referral program owner has the option to add an expiry for discount codes associated with their program. If your discount code has expired, that means they have limited the discount offering to 'X' days from the time you joined their referral program.

Once your discount code has expired, you are no longer able to offer the discount, however can continue earning commissions by sharing your referral link for the store.
