dont just limit yourself to one category. Everyone and their mother starts out thinking, electronics, and DVDs, computer related items...clothing, sporting goods....the market is way too saturated to make a significant profit unless you sell in hig volume. but you can diversify, and sell a little of every category, and you can start very small, sell a couple DVDs and see how they do,etc... in addition, you can look into real niches, that can make for better profits, if you find good niches, but dont just limit yourself to one category, unless you find something that works. a lot of it is trial and error, so if you are hoping for a 7$profit from a $3 DVD, just give it a try, experiment, list it for $10 buy it now AND also a .99 auction, and see what happens. also, list it on Amazon, the traffic on amazon is great. also, try craigslist,etc.. ioffer is also possible. anyway, just my 2 cents, what do i know, ive been trying this for years, and have only so far acheived nothing but debt. :) good luck.... there are a lot of experts on here though that i am sure can provide you with much better advice...
