Walmart offers the Bulldog Cases Standard Range Bag with Strap in Black, model no. BD900, for $15.20. (Amazon charges the same with free shipping for Prime members.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's slightly below last week's mention, the best now by $8, and the lowest price we've seen. It measures 13" x 7" x 7" and features a water-resistant outer shell, large main compartment, outer pockets, and adjustable shoulder strap.
