Home Depot offers the DeWalt 13.1" Tough System DS 300 Large Tool Box, model no. DWST08203H, for $34. (Amazon has it for the same with free shipping for Prime members.) Choose in-store pickup to avoid the $79 truck delivery fee. That's tied with our mention from three weeks ago and the lowest price we could find now by $8. It's constructed of 4mm structural foam and features an integrated water seal.
