Membership coupons

Is there a way or a mod to be able to create coupon codes to offer a free month of membership when purchasing a membership? I am using Paypal Payflow.

Thanks,

Dan

there is a module in the market that allows you to create discount codes - which you can setup for what you want. https://www.boonex.com/m/Membership_Vouchers

Thanks for the reply, I have emailed Anton to be sure it will work for my version of Dolphin and Paypal Payflow.
