Always on the lookout for the best value/price ratio. I buy generics for small purchases like canned food and toothpaste but for bigger purchases, its tougher.
I've never bought a new car and probably never will.
Scan craigslist for furniture and hardware.
For consumer electronics, I buy new but look for middle-end. Low-end is usually crap and high-end is just the middle-end with bells and whistles.
I've learned to pay a little more for clothes lately. I used to never want to go over $20 for a shirt. But I'd buy three and wear one. So now I just buy one for $4O and look damn good.
I also bought Ford at $1.35.
