What is a coupon?
You can earn coupons by referring your colleagues to Prolific. These are discounts that you can apply to new studies. The discount is only applied to Prolific's commission on the transaction and not to the rewards you pay to participants.
* Each coupon can only be used once
* You can use multiple coupons on a single study
* However, coupons cannot be combined with other offers (e.g., percentage discounts)
