Walmart offers the Fisher-Price Think & Learn Code-a-Pillar for $19.88. Choose in-store pickup to avoid the $5.99 shipping fee. (Amazon charges the same with free shipping for Prime members.) That's $5 below our mention from last month and the lowest price we've seen. (It's the best deal now by $5.) It features nine segments, a motorized head segment, lights, sounds, and blinking eyes.
