I know this is an old thread, but it's a good one. Here is my story, hope it helps someone out. Or at least make you laugh!
When I was 15, I did a summer co-op for a local computer manufacturer that sold PCs to government and large companies. Contracts for thousands of PCs at a time. This was back in the early 90's, when PC use was exploding and there was big money in clones.
My job, no joke, was to sort screws. They would give me a garbage pail sized bin of mixed screws, and I had to sort the big "hard drive" ones from the little "floppy" ones for 8 hrs a day. I had a stool, and a small spot on the end of a workbench. I got amazingly good at it. Somehow I picked up the nick name "the screw kid". Sometimes they would let me fetch coffee or lunch for the real techs who did assembly and repairs. Oh, did I mention this job was for school credit, and they weren't even paying me any salary?
Anyways, due to the volume they did, they got lots of returns on defective monitors, which were repaired in house. Company profits were good enough on their PC sales and customer service was so important for the big clients that any dead monitors were always replaced with brand new ones. Techs would fix up any of the returns, and they'd get used around the company or sold off to staff for use at home, just to recover some of the money. This meant that the tech room was always full of recently repaired 17" monitors, dozens and dozens of them in a constantly growing pile, still in boxes. The better the PC sales business got, the more the pile grew.
These monitors sold new for ~$350 at the time. I overheard one of the techs say he bought one for $175 - half price. So, one day I gathered up all all the courage I had and I walked right into the president of the company's office. I told him who I was (screw kid), and I explained that I worked hard for no pay, but I would really appreciate it if I could get the same price as the real employees on the used monitors. I don't know if it was out of pity or not, but he made the mistake of saying that I could have as many of them as I wanted, because they would be glad to get rid of them.
Big mistake for him, gold mine for me. I had been tinkering selling and building PCs at home, and I knew what stuff was worth. With local taxes, you couldn't get monitors like that for under $400. So, I bought 5 monitors for $175 each, and put a $12 ad in the local paper. "Mint 17" monitor, like new, $250".
The phone rang off the hook, I sold them all in one Sunday. Suckers paid $250, hardballers could get them from me for $225. I made $300 in one day. I had never seen so much money in my life, I couldn't believe it!
Then things went really crazy. I walked back into Mr. Presidents office on Monday and cut a deal with the boss to take more of them, but they'd have to let me have them for $150 each. He must have thought I was crazy, what the hell could I want all those used monitors for? But he didn't ask, and I didn't say. I think he was actually happy to have solved his "problem" of surplus monitors. But now I could make $100 for every monitor sold!
Every day my mom dropped me off and picked me up from work. Now, every night she'd pull up back and wait while I loaded the caravan as full as I could. The techs would talk amongs themselves about what the weird screw kid was up to, hauling monitors out with him after every shift.
From that little ad in the paper, the phone just wouldn't stop ringing. I told everyone that called they could come see them from 6-8pm. Often times, there was no place to park on the street, and I'd have a dozen strangers at the door. There was a parade of people coming to buy used monitors from my livingroom every week night. I made little receipts, and offered a month warranty, but none ever came back bad. Sometimes there would be a bidding war when there was only one monitor left for the day. Losers were encouraged to come back the next day for first shot at the next batch!
I cleared out the entire supply in a few weeks, it must have been over 100 monitors in total, because by the time it was all said and done I had well over $10K in profit. Enough to buy my first car, before I even had a license.
I got the last laugh on those smug techs who thought they were so smart. Any one of them (or the other 50 employees working at the company) could have done the exact same thing that I did. It wasn't rocket science, and I was no genius. I just saw an opportunity in a situation that others saw as a problem.
I learned a lot about business that summer, self taught the old fashion way. You don't have to be a genius to be a successful entrepreneur, you just have to be able to spot a opportunity when it presents itself.
