HAPPY BIRTHDAY!! Want and need? %&%$#? That's the question. I ask myself the same question. I don't use a machine myself, but there are many things I do, that are expensive. I think it's a good deal. The least expensive carts I've seen have been at Michael's on sale at Christmas. They were marked down to $35-$40 per, and almost sold out. So I think your Peppermint Cricut is a great deal with all 4 carts. I hope you had a VERY HAPPY BIRTHDAY!! Go for it!!
