General supermarkets do snacks in terms of how much profit, and how to buy goods can be more profit. The location is Beijing

Look at how big you want to open. If you want to sell a lot of thin margins in the size and location to choose up and down a bit of effort; such as the size and customer population is limited from the unit price of goods;

Simple example: such as a packet of noodles, the purchase price of general 1 yuan 2,3, you can sell 1 yuan 5, you can sell 2 yuan, such as the heart of the black point, you can sell 2 yuan 5.。。。。 Depends on your specific location and the actual situation, such as your store near more peers, the price is you can not be too high, otherwise the pressure of competition is absolutely great!

Access to goods in general in the big point or centralized point of the wholesale market wholesale, you'd better contact 2,3 fixed wholesalers, so that the purchase price can be preferential.

Because I'm not in Beijing, Beijing is not very clear, you can check online.

I hope you are a bit inspired!
