The Postal Scale that


 eBay Sellers Need!



A question I often get from my students is:


“How do I know how much to charge for shipping, when I don’t know who my customer will be and where they live?”  The good news is that we no longer have to guess the postage rate. eBay has solved this for us if we use of an accurate, digital scale.


When you create a listing, you determine whether the shipping charge will be:

            1. Flat Rate, which is the same cost for anyone in the U.S.  

                        - or -

            2. Calculated Rate, based on the total weight, destination and

                shipping service


If you choose #2 Calculated Rate, then you will need to provide eBay with three things:

            1. Total weight of the package   (item in the box with packing material)

            2. Dimensions of the box   (L x W x H)

            3. The Carrier and shipping service  (such as USPS Priority Mail)


With this information, eBay knows your location and how you will ship the product. When you have a winner of your listing, eBay now knows where your customer is located. eBay can then calculate and automatically add the cost of shipping to your customer’s invoice. Your customer will then pay for the item along with the correct shipping charge.  


To determine the proper weight, you will need an accurate digital postal scale. It must be as accurate as the scales at the post office. Note that there is nothing magical about the word postal in postal scale. It is not a postage meter, but rather a very accurate digital scale used for weighing packages, tubes, envelopes and other items. You will use it to weigh the item in its shipping box along with all packing materials, then note the total weight (pounds and ounces).




My recommended scale for eBay sellers is the UltraShip 75, by MyWeigh. It is rated for weights from ¼ oz to 75 pounds (34 kg). That range will certainly meet almost all of your eBay selling needs. This scale costs less, is better quality, and has more features than the postal scales sold by the Post Office or in office supply stores.

You can also use this scale to weigh items in the kitchen, garage, and basement. I routinely use mine to measure the weight of my fully packed suitcase, so I don’t exceed the 50-pound weight limit of the airlines. Whether you are weighing food, postcards, letters, parcels, envelopes, padded envelopes, mailing tubes, or assorted size boxes, the UltraShip 75 will be a precise and durable shipping scale for you.

Some online Sellers (including eBay and Amazon) claim to be authorized dealers (even wholesalers) of this scale, but they are not. These sellers advertise the scale as new but sometimes ship a refurbished unit or an outright knockoff. Their buyers receive a cheap, inaccurate scale with no manufacturer’s warranty. If you see an unusually low price for a new scale, that is the tipoff that the dealer may not be selling a genuine or new product. This is fraud. To help avoid this for my students, I now offer the genuine UltraShip 75 scale. Your complete satisfaction is my primary goal.
