開鋪為與趣, 個人認為唔易earn money unless you can find a very good shop (with cheap rental and good location) and you have network with wholeseller and factory.
I have some customers who also shop from yahoo auction and skybaby, they will compare the price. Of course, mine will be very expensive because I need to pay for rental and salary.
You need to be able to buy some special brands and nice clothes.
I am helping two mommies to set up their shop, if you need support, you can contact me.
