My tip is invest in a lights timer. You can find these at your local home improvement store for about $5. You plug them into the electrical outlet and then plug the device into the side. The device will not turn on until the designated time on the timer. Here are a couple great uses for it:
Put it on a lamp in the front room of your house. Set it to turn on at dusk and you will never come home to a dark house again!
Plug the crock pot into it and set the timer to run for the exact cooking time. No more burnt or dry food because you didn’t make it home in time to turn the crock pot off!
