To celebrate the 25th anniversary of Stampin’ Up! in 2013 they will release a set each month. These will have 4 favorites from retired sets and one new stamp in each set each month. They will cost $14.95, and for each one you purchase one, you will get a sticker. When you purchase 6 of the Best of Stampin' Up! sets you’ll get to pick a free $14.95 set. You will get a special sticker with each set and you can save them on a card to redeem at the end of the first 6 set purchased. If you purchase all of them you get two free sets.
