Walmart offers the GE 60-watt Equivalent 15-watt Bright From the Start CFL Light Bulb 2-Pack for $3.99. Opt for in-store pickup to avoid the $5.97 shipping charge. That's tied with our mention from last week at $2 per bulb, $9 off list, and the lowest we've seen for a 2-pack of these bulbs. They output 800 lumens and last approximately nine years.
