USPS is often cheaper than FedEx when shipping packages that are not up to 2lbs. FedEx can be a cost-effective option to consider when shipping packages more significant than 2 lbs as it offers a cheaper rate. However, if you can package your goods into a small, medium, or large flat rate box, then USPS is certainly cheaper than FedEx.
 Cost-saving tip: The truth is that - your cheapest options could be FedEx or UPS if the package you are sending doesn’t exceed 2 and 5 lbs because they handle dimensions, and not weight. Small shipments like that can fit in smaller boxes and, thus, cost you between $12 and $25, based on the size of the box you place the packages.
