Walmart continues to offer the Spy Gear Batman Utility Belt, model no. 5521399, for $8. (Amazon has it for the same price for Prime members, and Target has it for a few pennies more via pickup.) Opt for in-store pickup to dodge the $5.97 shipping charge. That's tied with our mention from last week and the lowest price we could find by $7. It features a motion alarm, adjustable strap, three accessory compartments, and requires two AAA batteries (not included).
