Hmm...Business?

I've been doing some thinking and I've decided to put up a small online business to earn some extra cash.
The problem is, I can't decide what to sell.
I know it's difficult to find a unique item since there are so many online resellers nowadays.
I'm choosing between soaps, bags or clothes.
I want to sell something that I'm interested in.
I've already sold stuff on eBay but I'm planning on stepping things up and taking this more seriously.
Sigh...
Hopefuly I'll be able to make a decision soon.
