Sing-a-ma-jigs are on sale right now at Fisher-Price.com. They are originally $13.00 and are all marked down half price to $6.50, even this cute Easter one. This sale will last through 4/10/10. Shipping on purchases $20.00 and under is $5.99 though and sales tax may apply.
My daughter got a couple of these for Christmas from my in-laws and they are really cute and fun to play with.
