Walmart offers the Dirt Devil Gator 10.8-Volt Cordless Handheld Vacuum Cleaner, model no. BD10100, for $22.99. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to avoid the $4.97 shipping charge. That's the lowest price we could find $3, although we saw it for $3 less in February. It features a built-in crevice tool and easy-open dirt cup.
