need to double the order by coupon

Hello

The customers needs to double any product in the cart by entering coupon DOUBLE.
I mean i the user have 1 product X in the cart, it will become 2 at price of 1.
We managed to double the qty by using get_products() and update_cart() methods in the shopping cart class.
BUT, the price is doubled as well, and this is bad.

Also tried Better Together module, same thing.

Any help would be highly appreciated.

Thanks

Re: need to double the order by coupon

You're going to need to do a little custom coding for this.

This example:
http://www.zen-cart.com/wiki/index.php/Developers_API_Tutorials#Another_Real_World_Example

shows how to do buy-one-get-one-frees. You'd need to vary that code a little and need to make sure that that code got invoked only when the correct coupon code was entered.
