Walmart offers the Learning Resources Anatomy Models Set, model no. LER3338, for $45.28 with free shipping. (Jet.com and Amazon charge the same.) That's tied with our mention from a month ago and the lowest total price we could find by $5, although most merchants charge $60 or more. It includes four models with stands and illustrated instructions.
Walmart offers the Learning Resources Dizzy Fun Land Building Set, model no. LER9199, for $31.67. (Target and Amazon have it for the same with free shipping.)

It develops sensory, communicative and cognitive skills and requires two AA batteries (not included).
