Today only, December 20th, you can save 50% off the Barbie Dreamtopia Rainbow Cove Dream House when you clip the Cartwheel coupon to add it to your account. Once you clip the coupon head in-store to purchase! It looks like you can grab this for as low as $24.99! It is currently on clearance online and at a number of Target locations for $49.99. If you can grab it for this price and use the Cartwheel coupon you are scoring a killer deal!
I would call your local Target and see if they have any in-stock and at what price, then have them hold it for you at Customer Service. Good luck!
