How do I use a product attribute as a condition for a point rule?
When setting up point rules, you'll notice you can set conditions or restrict actions based on product attributes.
If you want to use a product attribute not listed here, you'll need to modify that attribute.
Navigate to Catalog > Attributes > Manage Attributes and click on the attribute you want to use in your rule. Expand the blueFrontend Properties bar and look for the setting Use for Promo Rule Conditions. Make sure this is set to Yes.
Now if you go back to your rule setup, you'll see this attribute included in the list.
