The list of retiring products will be out Monday, April 21st. Stamps will be available until the new catalog comes out however accessories will only be available while product lasts. Traditionally, many of these things sell out quickly, especially anything in the retiring 2012-2014 Incolors.
If you have any of these ink pads you might want to get ink refills and paper now while availability is guaranteed. Other things in those colors include ribbon, Dahlias embellishments, and markers. Also keep in mind that ribbon colors tend to change with the new catalog and all Designer Series Paper usually will retire.
