i am wondering what add-on i should get to get the following task done.

I am selling greeting card, some of my greeting card will allow user to selected banner they want for free ..

so what add-on should i buy that allow me to give 1 free items to every greeting card they buy. It mean like if they buy 10 greeting card they get 10 banner ( customer select them from big list ) for free.

1 greeting card get 1 banner free -
-- customer can select 1 banner out of 100 diference banner catalog.

I know special offer from x-cart add on have similar function that allow to do buy x get y free .. somehow i test with the demo page it would not work as the way i want at all ..
