title: How to create custom messages in magento when a user adds an item to a cart?
body: <p>First I wanted to create a new attribute.  Let's call it "Price Factor."  Integer values can be set from the product page on the admin control panel.</p>
  
  <p>On the front end, whenever a user adds an item to the shopping cart, a message pops up in the shopping bag and says "Your old price was X and your new price is Y" (where X was the original price and Y is the adjusted price.)</p>
  
  <p>How would I go about create a custom message when someone adds something to their shopping cart?</p>
