Low budget source for electrical parts

I got a good electrical power tip from a reader named Kelly that I thought was worth sharing here.

Kelly has discovered that most thrift stores have cheap wall warts that are looking for a good home.

We don't have many thrift stores in my region, but when I lived up north I recall huge second hand stores that would usually sell a power transformer/wall wart in the 1 to 2 dollar range, which can be a 15 or 20 dollar savings for any mechanical deer deterrent projects you may have in the future.

Thank you for the feedback Kelly.
