Nowadays, almost every networking sites there will always be an online shop @ Multiply, Facebook, Friendster, etc. You can sell all what you want, yet, try to think for those items w/c are sellable. Such as, perfumes, watches, shoes, and all sort of vanity stuffs. Being a seller be responsible enough not to sell fake ones, am not saying selling fake ones are that bad, but consider others, selling fake ones but admitting it as a genuine one.
And it's sure a big income! You'll save Rent expense, water expense and all sort of expenses when having a real store standing.
If you're planning to have one, go on. there's nothing to lose it's just Perseverance and a little bit of courage :)
