Apart from being an employee, I made my first £600 in business by buying up all the clearance bargains at the electrical store (Currys) I worked at and reselling them on ebay. They have banned it since
I then reinvested the £600 by buying DVD Recorders & Air Purifiers from the Sharp Factory Store in Manchester before it closed. I bought the DVD Recorders for £85 (Currys were selling them for £250) and resold them on eBay for £160. The only thing was that you were supposed to be a business in order to purchase from there so I used a name of a small independent electrical store every time I went to buy anything. After I knew how well they sold I started funding the purchases with my credit card, because I knew that by the time the bill came I would have sold the stock and would be able to pay it off. After 3 months I turned the £600 into £8,000. The other good thing about buying from there was that everything had a sharp warranty. So if anything ever went wrong with a product you could just tell the customer to get in touch with Sharp.
