Staples offers the GE Reveal 60-watt A19 Incandescent Light Bulb 8-Pack, model no. 90164, for $2.99. Plus, Staples Rewards members qualify for free shipping. (Not a member? It's free to sign up.) That's a buck under our mention from two weeks ago, the lowest total price we could find by $9, and a strong deal for this quantity of such bulbs. They have an estimated energy cost per year of $7.23 based on 3 hours/day and a 1,000 hour lifespan.
