What you need to know for the Catalog Transition: Friday, May 31st, through Monday, June 3rd, you'll be able to order from both the Retired Lists and from the new Annual Catalog. Since the 1st falls on Saturday, Stampin' Up! decided to overlap the ordering periods so that if anyone needs to contact them with questions, customer support will be available.
In addition, you need to be aware that on Friday, May 31st, online ordering will be unavailable from midnight to 12 noon while Stampin' up! adds the new catalog items to the online store.
If you don't have your copy of the 2013-2014 Annual Catalog yet, you'll be able to view it online tomorrow. See yesterday's blog post if you need a copy of the catalog.
That should be all you need to know about the catalog transition, but if you have any questions, be sure to email me at firstname.lastname@example.org.
