Walmart offers the As Seen on TV Pillow Pet Glow Pets Rainbow Dog for $9.88. (Kmart has it for the same price.) Opt for in-store pickup to avoid the $4.97 shipping charge. That's $20 off list price and the lowest price we could find. This stuffed animal pillow lights up.

Update: Kmart now offers it for $4.99 with in-store pickup.
