回複：$1 真的做不下來，$2 差不多

I think my product is simpler that the paper toilet. Can you share some details of where the cost come from? For example, the initial print fee, material cost, laber cost, and packaging and shipping?

Did you actially make menoy from that product? What's your best way to reach your customers, online ad or through retail chain. If your product is a new product, how to let the mass market know your product without dig deep hole in your bank account?

Thanks very much.
