Most of the supplies that High Voltage Christmas uses are standard off the shelf parts. The best deals are often at local stores who sell Christmas supplies at a leader loss. Still, the parts can be quite expensive. One of the biggest expenditures every year is the lights themselves. The lights High Voltage Christmas uses are available locally from Target, Home Depot, Lowes and OSH/Sears. Most of the low current extention cords used are also from those stores. A few of the cords are actually cable harnesses which are custom built for the display. The bulk cable and specialty cable also comes from local stores like Pete's ACE Hardware.
