Walmart offers the Nickelodeon Super Mario "Defiant Mario" Room Darkening Curtain Panel, model no. MU455C, for $9.97. Opt for in-store pickup to avoid the $4.97 shipping fee. That's $2 under our mention from last September and the lowest price we've seen. (It's a current low now by $3.) It measures 42" x 63" and fits a 29" wide window.
