If this doesn't catch your attention, then you are not a avid decorator. If you are a NEWBIE...just remember....YOU CAN NEVER HAVE ENOUGH EXTENSION CORDS! You will always need more.
Ok.... what is a good source for extension cords? YARD SALES! I have found TONS of cords at yard sales over the years. Great deals too. People who are moving normally don't want to fool with that wad of tangled mess in the box of cords. I have gotten boxes of cords for just $10.00 before. Turns out it was somewhere around 300 to 400 feet of cords.
Look for those deals after Christmas too. Many places will put those green cords in with the Christmas stuff too. Half price is always good ;-)
