title: Magento Shopping Cart Price Rule: SKU option is not visible in Actions -> Conditions
body: <p>I'm using Magento V 1.9.0.1 and I tried to add the <code>Shopping Cart Price Rule</code> =&gt; <code>Buy X Get Y</code>.</p>
  <p>I followed the steps in the magento <a href="http://www.magentocommerce.com/wiki/3_-_store_setup_and_management/shopping-cart-price-rule-recipes#buy_x_get_y_when_x_is_not_1" rel="nofollow noreferrer">guide</a> but as I proceed I found out that the SKU option is not available when trying to add the condition.
  The screen print is below.</p>

  <p>I'm new to magento and I cannot understand why the option is not visible.</p>
