The description said: The May Mystery box includes 4 cartridges any crafter will enjoy. The contents are a mystery, but they're a $139.96 value.

Contents of box with prices from the Cricut website listed.
The first price is the regular price and the second price is the sale price listed.
Cricut Straight from the Nest Cartridge. Value = $39.99/$23.99
Cricut Potions and Spells Cartridge. Value = $29.99
Cricut Summer Celebrations Cartridge. Value = $39.99/$19.99
Cricut Jubilee Cartridge. Value = $29.99/$19.99
The total value of this box is $139.96 or $93.96. I really think Cricut should calculate the value based on the current prices. Yes if you bought all of the carts at retail price it would equal the promised value, however on their own site the price is lower. It's still a great value with a $50 savings but it's misleading. Surprisingly I have over 70 cartridges and I had none of these. I thought I had the Jubilee one at first but as it turned out I didn't. One of these days I'll post a picture of some of my creations, but I have to make something first.
Verdict: If you are into Cricut and don't have a lot of cartridges the mystery boxes with cartridges in them is a great deal.
