@slesiuk,
That would depend on your definition of "earn". My definition is if I have to spend money, I want to spend the least amount for a product or service that is out there to meet my needs.To me that can be earning.I have so many tips on how to save money it really isn't funny.
I have saved lots of $ by what members write on this site and doing the research on the internet.That all takes time though.
The most recent example I can think of was to re-wire a electrical connection.I did do it and yes I turned the main power off.
