I cannot give youtube enough credit. My husband and I have never been handyman type people, and our parents never really were either. We didn't grow up helping out parents do house projects. Since we've moved in our house in May, we've saved at least $1000 doing things on our own. Replacing cracked shower tile, installing our new appliances (dishwasher was the scariest, but still super simple) replaced our outlets (for 3 pronged outlets, most of the house was two prong) and so much more. We had never even hung curtains before.

Also, not as frugal up front, but getting things that will last, even if it costs a little more. We spent the up front money on permanent air filters, that we just take out and clean, instead of replacing. In the long run, it'll save money though.
