It depends on what kind of goods you make. For first-class wine, this problem is not what you should consider. The manufacturer has a national unified price, so you don't set the price. This will prevent cross-selling problems.

For example, Maotai takes delivery in Beijing and 50 yuan, and Shanghai and 5 yuan take delivery. Aren't all the goods shipped from Shanghai to Beijing? What do dealers in Beijing do? So the specific profit is different. For example, if you buy 100 in Beijing, you get 10; if you sell 100 in Shanghai, you get 12.

If second-class goods, or miscellaneous goods, have several prices. The principle is that the delivery price is about 40% of the retail price and the delivery price is 85%-90% of the delivery price. I will say the delivery price myself.
