Walmart offers the Nerf N-Strike Modulus ECS-10 Blaster for $26.54. (Amazon charges the same exclusively for Prime members.) Opt for in-store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find today by $4 (most retailers charge $41 or more), although we saw it for $5 less Thanksgiving Day. It features removable parts for customization in more than 30 configurations, a targeting scope, drop grip, dual-rail barrel, and 10-dart banana clip with included darts. It requires four AA batteries, not included.
