How to find the cheapest and fastest shipping options

While finding all available shipping rates is easy enough, how do you find the cheapest option and the fastest one? Not everyone has a week to wait for their package to arrive. In today’s “get-it-now” world, getting your packages out to your customers — or even to friends and family — in the shortest amount of time possible matters.

To find your quickest shipping options:

Under your estimated shipping costs, look at the third column, labeled Delivery Days.Tap the Delivery Days column to sort your carrier options by the number of days it’ll take for your package to arrive at its final destination. You may see delivery day options as short as one day or durations as long as weeks, depending on the ship-to destination.

To find your cheapest shipping options:

Look at these four columns in the estimated shipping costs: Retail Rate, Discounted Rate, Amount Saved and Percent off. These costs are all tied to how quickly your recipient(s) will receive your package in the Delivery Days column.Sort any of these columns to display the lowest rates (or largest discounts).Once you’ve selected the option that fits your budget, purchase your shipping label, prepare your package and ship!
