There are 24 new additions. But instead of full cartridges or mini cartridges these are single files that you use to create a card. I love this idea!
They are $1.99 each except for five of the cards which are free to use in CCR until June 19, 2012!
Check out all the card samples at cricut.com in the Today's Deals section.
ETA: Currently only the 5 free carts are showing up in CCR. You won't find them in the CCR Exclusives library but in the My Cartridges library.
When you purchase one of the other 15 carts it will also show up in your My Cartridges library - not the CCR Exclusives library.
