business hit

My best friend during high school and her husband are into wholesale housewares reselling. If I'm not mistaken, they've been in the said line of business for almost a year now, it was a new thing here in our city that is why they really boomed and was forced to get another branch for their stocks and customers are already complaining on the small place they have. And I am one lucky gal to snag so many sale items for the house! Even the Christmas decors that we had last year were mostly from their store! All imported but are all so cheap!
I wonder if that kind of business will also be a hit thing in another provinces and cities... You see, the husband and I were thinking of what business to enter once he comes back.
