Walmart offers the Great Value 8.5-watt (60-watt equivalent) A19 LED Light Bulb, model no. GVRLA6027ND, for $2.44. Opt for in-store pickup to dodge the $4.97 shipping charge. That's tied with our mention from a week ago and $2 under the lowest price we could find for such a bulb. It features a 2700K color temperature and 800 lumens of brightness.
