I got this in an email this morning, good for the first 500 customers. Here is the link:
Buy one of the following Cartridges or CGull Expression tote and get a FREE CRICUT JUKEBOX $90 Value!!
The cartridges I looked at were $70. Not the cheapest, but if you're getting the jukebox too it's probably not a bad deal! You need to put both the cartridge and the jukebox into your cart and enter the coupon code "summer" at checkout.
