Amazon offers its Prime members the Mega Bloks First Builders ABC Spell Playset for $9.08 with free shipping. (Walmart charges slightly more with in-store pickup. Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $6.34.) That's the lowest price we could find by $4. The set includes 40 blocks and a carrying case. It's recommended for children ages 1 to 5 years.
