FedEx and UPS provide far more options for time-sensitive shipping, with guaranteed delivery as early as 8 a.m.To find the cheapest shipping rates, we compared the cost of sending hypothetical 5- and 10-pound packages coast to coast, from New York City to a residential address in Los Angeles. Pricing generally varies based on the size and weight of the package and the origin and destination, although all three carriers provide flat-rate boxes that ship for a fixed price regardless of weight.
