title: Buy X Get Another X Free Magento
body: <p>Trying to find out how I can create a rule in Magento where you buy x product and you get another x free automatically but has to work more than once so if you buy 2 X you get 2X More free.</p>
  
  <p>Also it has to work with to different SKU's </p>
  
  <p>Sample Scenario will be in my cart i have 1X SKU is 001 and 1x 002 on my rules 001 and 002 are included on the promo so 002 will be free. But if add 4 items from product X with sku 004 2 of them are free as well.</p>
  
  <p>I want the cart to be able to calculate for each 1 you add to cart you get 1 free from the group of sku's but they can be mixed i don't want the to be 2 of same kind.</p>
  
  <p>So Buy X Get 1 Free from a group of sku's and cart must be able to know that if i have 3 more are free but the problem is if i only have 3 items it show as a total of 0.00 making the cart free.</p>
