Buy N products for set price + free shipping - recommendations?

Hello. We require a promo code to be automatically applied when N products are added, with the discounts being a set price and free shipping. What apps can offer this?

@satellitecam You can make a promo like N items for $Y fixed price with our app. If you meant to have a fixed discount (e.g. $20 off), it is possible too, of course. 

About the free shipping, when you create the custom deal, there will be a section near the bottom to enable free shipping.
