Hi, I will be in Yiwu to buy hardware and plumbing items for business.

You can go to the local International Trade City. As far as I know, there are many shops at 4th Floor, 2nd Region that sell all kinds of hardwares and plumbing items.

I have no the exact price, but most products have low price and good quality. About the concrete discounts and amounts, you need to consult the exact shopkeeper. Before you buying the products, you can compare the price to other shops. Choose the most suitable one. :-)
