Tips for reducing the shipping cost

1)Get rid of the original packing, for example, if you buy a pair of shoes, you could get rid of the shoebox which will save a lot for volumetric weight.

2)The shipping cost is normally charged by every 0.5KG. So if you buy a product that is only 0.1KG then you might consider buying 2-3 PCS per time which will not add more shipping cost for your order.

Volumetric Weight

Volumetric weight refers to the overall size of a parcel and is measured in volumetric kilograms. Volumetric weight can be calculated by multiplying the length, width, and height of a parcel (in cm) and dividing that figure by 5000 (some carriers use a divisor of 6000/7000 and etc).
