Mostly by using "how to videos" on youtube.
I have gone to videos on youtube and found that repairmen were wrong/lying and did the job myself for 20 times less then their estimates($800 job done for $40).
I've order products for better prices online.
Saved gas on shopping because I find the product and store online first then go out and buy it.
Unfortunately though, surfing this site is going to cause me to spend all the savings on psychotherapy.
