Though the exact terms of economy shipping vary depending on the shipping company, in general, it is a budget-friendly form of shipping that normally takes longer than other options. Economy shipping is a suitable option for businesses that are concerned with keeping costs down or for deliveries that are not urgent. Weight and content restrictions for economy shipping services are prevalent.
For example, FedEx offers international economy shipping that offers a transit time of approximately 5 business days and has a weight limit of 150 pounds, as of February 2015.
USPS offers Standard Post and Media Mail as economy shipping options. As of February 2015, both can take up to 8 business days, and Media Mail is only an option for materials that are deemed educational.
