Darren, don't worry about the sale ending soon, a week later it will be on sale again. X-10 come always has a sale going wich is cool.
this is what I posted almost two months ago
if anyone is interested in learning more about the firecracker set up or just X10 in general you can follow this link
"X-10" by regestering at this page you will get a 15.00 credit on your first order. I did this and ended up getting my firecracker kit for 37.00 including tax and shipping.
anyways I just wanted to let you all know that as soon as this sale ens there will be another and so on and so on so you don't have to jump into it if you are not sure yet.
