Home Depot offers the Crescent 20-Piece X6 Pass-Thru Ratchet and Socket Set, model no. CX6PT20, for $28.56. (Amazon offers it for the same with free shipping for Prime members.) Opt for ship to store pickup to dodge the $5.99 shipping fee. That's the lowest price we could find by $3, although we saw it for a buck less in April. It includes standard and metric sockets that work with six different types of fasteners.
