Looking for a module to enable prepaid products

[Noorlander]

Hey,

 

I have a requirement for my store for users to be able to use a voucher that will give them the right to purchase 1 particular product "xyz" as no cost, regardless of the price of the product in the store. Ie: regardless of product "xyz" sales price, 1 voucher = 1 free product "xyz"

 

Does anyone know a module that allows for prepaid products (not prepaid credits).

 

I should work like this:

* user selects a product "xyz" and adds to cart

* user enters voucher code

* 1 product "xyz" is free

 

So i have tried setting up a standard cart rule:

* Information => Partial use = No

* condition => Total available for each user = 1

* Action => Apply discount % = 100%

* Action => Select specific product = product "xyz"

 

This works, as long as the user only has 1 product "xyz" in his cart.

If the user has multiple products "xyz" in his cart, they are all free (despite the condition)

 

I cannot use:

* Action => discount fixed amount, as the price of the product will vary depending on user, location, and time

 

I have search long and hard for an existing module. However, every module i found provides prepaid credits, not prepaid product.

 

Does anyone know of a prepard product module, or another way of achieving this?

 

thanks
