Amazon offers Prime members the TCP LED A19 60-watt Equivalent Light Bulb 6-Pack, model no. LA1050KND6, for $18.49 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $7.12.) That's the lowest total price we could find by $6, although we saw them for a buck less two weeks ago. They feature a 5,000K "daylight" luminosity and consume 8.5 watts.
