Ace Hardware offers Ace Rewards members the Craftsman 6-Piece Plastic Spring Clamp Set for $4.99. (Not a member? It's free to join.) In cart, the price falls to $2.99. Opt for in-store pickup to avoid the $6.89 shipping fee. That's the lowest price we could find by $10. The set includes two each of 1", 2", and 3/4" clamps, each with a pivoting jaw. Deal ends December 24.
June brings some big deals and sales, but you're better off postponing certain purchases.
