Economic : It is usually the slowest and cheapest type of shipping that can offer the seller, rarely including a tracking number and signature. It is ideal for low value items.

Priority : It is usually a fast type of shipping (by air for international). It sometimes can enable real time monitoring of the delivery if the postal service offers a tracking number.

Registered : It is usually a fast and secure type of shipping providing legal evidence of delivery and sometimes an insurance for the seller in case of loss or breakage.
