title: Cart Rules base on QTY in magento
body: <p>I have one group product. And i have two product in group one is the 1 bottle and one is 6 bottle product.</p>
  
  <p>Now i want to set free shipping based on the product qty so i have used flat rate shipping method.</p>
  
  <p><strong>Now problem is</strong>  when customer purchase 2 qty of the 6 bottle package than each package contain 6 bottle so it will be 12 qty but in cart it shows only 2 qty so flat rate will not apply.</p>
  
  <p>Second problem is Customer purchase 1 package of 6 bottle and 6 single bottle qty in cart is 7 but actually it has 12 bottle</p>
  
  <p>so in this case how can i create shopping rules or flat rate.</p>
  
  <p>Please suggest me idea on it.</p>
