Walmart offers the Nerf Zombie Strike FlipFury Blaster, model no. A9603, for $14.39. (Amazon charges the same for Prime members.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's the lowest total price we could find by $6, although we saw it for a buck less in April. It features two dart drums and fires up to 12 darts without reloading.
