Amazon offers Prime members the TCP 60-Watt Equivalent Daylight A19 Non-Dimmable LED Light Bulb 6-Pack, model no. LA1050KND6, for $34.66 with free shipping. (Non-members can pad their order over $35 to bag free shipping; otherwise, it adds $7.28.) That's the lowest total price we could find by $10 although we saw this pack for $5 less in winter.
