If you live in North Carolina, South Carolina, or Ohio then this is for you. Duke Energy is offering their customers a free box of Compact Fluorescent Light bulbs (CFLs). They claim that this can save you $30.00 a year compared to regular incandescent light bulbs, and that’s pretty nice considering they are free. A free 6-pack will save you about $15.00 alone! So I’m going to consider that a $45.00 savings for the year! To learn how to get your free light bulbs go to the link below.
