Which logistics transportation is cheaper?

China Post and Debon Express. If you want to be cheap and don't need time, the cheapest one can be ordinary parcel (surface mail) of China Post. Generally, the starting price of postal service is only 5 yuan, and the subsequent price is only 2 yuan per kilogram. However, this kind of surface mail is mainly because the time is much slower, and it is the cheapest mailing method in China. Debon is a cheaper express delivery, and sending large luggage is the most cost-effective. Generally, large luggage is charged according to the price of the first weight plus the continued weight, but some items will be charged according to the volume because the volume is greater than the weight. The specific freight needs to be calculated according to the actual goods and regions, and the freight gap in different regions is also very large. Debon Province 10kg price 24 yuan; 20k g 39 yuan.
