Extension Cords

I finally took the plunge and bought a spool of SPT wire. I found out this really takes a ton of extension cords. I bought all the cords Target had at Christmas last year, approximately 75 cords of different lengths. After getting most of my display put together, I decided I still didn't have near enough. I bought another 1250' of SPT1 wire to make my own cords. It actually came out to be just 16 cents a foot this way. If I was to go to Lowes and buy this length of pre-made cord it would be around 46 cents a foot.
