Toys"R"Us offers the LeapFrog LeapReader Reading and Writing System in Green, model no. 21301, for $16.79. (For Prime members only, Amazon charges the same with free shipping.) Opt for in-store pickup to avoid the $5.99 shipping charge. That's tied with our mention from a week ago and the lowest price we could find today by $5. Designed for kids ages 4 to 8, it purports to teach reading, comprehension, phonics skills, vocabulary, writing, and letter forms.

Update: The price has dropped to $15.99.
