These brushes were released last season by Target and they're available on the website right now for $7.99 with free shipping.
I'm not sure how long this deal is going to last, but I think it's a good price. I own a full set of Sonia Kashuk brushes and the quality for the price is unbelievable. If you use ebates you also get 3% back.
These would also make great stocking stuffers or last minute x-mas presents!
