I noticed that the Crayola Color Wonder items were marked down to 70% off at my store (Federal Way). These were priced at only $1.49 (reg $4.99). Clearance prices can vary, but If you are headed to Target you may want to see if you can find the same discount. I have heard from a couple of people that they have found the same.
I would pick these up now and save them for stocking stuffers for Christmas.
