Shipping prices are based on product weight, shipping service, and destination. We always try to provide the fastest service at the lowest price. Firstly we consider the delivery time and, if two services have the same delivery time, we choose the cheaper one.
The reason we can’t offer the same price for all the products and for all the countries is that some products are considered dangerous, like for example liquids, and the different weights and volumes change the price of the shipping by a lot.
Then you have to consider the country and the shipping services, not all the shipping services are available in all countries.
So we always try to offer the best service considering the delivery time and the price thus the different prices for the different products and countries.
If you want to see the shipping price of a specific item to a specific country, you can check in the Product Tab > select a product > click dropshipping > Shipping Tab and select the countries where you want to ship to.
There you will see all the shipping services available for that country with their prices. Our system's default shipping method is always the fastest available. Without considering Premium Special Line and DHL that been express lines are exceptions.
