Time is running out to take advantage of the ability to purchase the retiring stamp sets and bundles. All of the current bundles (stamps + dies/punch) go away on May 31. While many of the individual items in the bundles may carry over to the new catalog, they will not be bundled together, saving you 10%. Stampin' Up! never puts stamp sets on the clearance rack (they donate any left over stamps) so if there is something in the annual catalog or the Occasions catalog that you particularly want, you should get it while you can. You really don't want to have to try to find these things on Ebay later, as those prices are always very inflated.
Are you excited about the new catalog? I certainly am. The new catalog will go live around noon MT on June 1. But Stampin' Up!'s website will be down from midnight until they get everything loaded for you to purchase. They anticipate that it will be noon but could come up earlier. If you still need a catalog, just request one and I'll be happy to mail one out to you!
