Wow!  The Grab Bags are going fast!  Here is an update from Stampin' Up!:

As announced on April 1, for a limited time we are offering $5, $10, and $15 grab bags on Demonstrator and Online orders. So far, many people have taken advantage of this offer–so many in fact that the $15 grab bags are already sold out. In order to keep a $15 option available, we’re now kitting together a $10 and a $5 grab bag to fulfill $15 grab bag orders. The value of the products you will receive is unchanged. 

Whether you are interested in a Grab Bag or not, you should definitely check the Clearance Rack for some great deals!

Let me know if you have any questions!
