Warehouses in different countries may use different logistics methods.
Shipping methods we use: POST, E-POST first class, FedEx, UPS, DHL, SF-Express, etc.
Different logistics methods are used for different countries and shipping from addresses.
For example, in the US, we will prefer the FBA channel. You can choose Standard, Expedited (2 days), Priority (next day). When FBA is not available, we will ship from a warehouse in New York or California. When the US has no stock, we will ship it from other countries. If you choose Expedited or Priority, you will receive it 3-5 days or 2 days after delivery.
