At Sears, Shop Your Way Rewards members can buy select Craftsman batteries and chargers and get at least 50% back in SYWR Points. (The points are valid for 14 days. Not a member? It's free to join.) Opt for in-store pickup where available to avoid shipping charges, which start around $5, or get free shipping on orders of $49 or more. Some exclusions apply. A couple of best bets, with comparisons assuming you'll use the credit:
Sears offers the Weller/Portasol Professional Self-Igniting Cordless Butane Solder Kit, model no. P2KC, for $39.99. Opt for in-store pickup to avoid the $4.49 shipping charge. That's tied with our July mention and the lowest price we could find by $13. It features Piezo ignition, adjustable temperatures up to 850° F, and up to one hour of continuous use.
For in-store pickup only and with stock varying by ZIP code, Sears offers the Craftsman 150-watt to 230-watt Solder Gun, model no. 54046, for $19.99. That's $2 under last week's mention, $20 off list, and the lowest price we've seen. It features a replaceable heating element and nickel-plated steel construction.
