Walmart offers Eric Carle's My Very First Library for $13.25. Opt for Site-to-Store pickup to avoid the $4.97 shipping charge. (Amazon offers it for the same price for Prime members.) That's the lowest total price we could find by $8. Titles include "My Very First Book of Colors," "My Very First Book of Shapes," My Very First Book of Numbers," and "My Very First Book of Words."
