Stamps.com Plugin – Sending options not available when calculating shipping costs


Some sending options are not available when calculating shipping costs: It seems that over a pound the First Class option isn’t available. Could that be a setting?

We are also experiencing incoherences in shipping charges “Priority mail”, for instance being 9 dollars for a 1.12lbs sending, and then 7 for a higher weight.


First class mail shipping mail can be use to ship items weighing up to 13Oz.

Since 1 lbs= 16 oz, so that’s why you are not getting first class mail as a shipping option for items weighing more than 1 pounds.

For the issue with Priority Mail, we request you to check the Parcel Packing option at your side.

You can set the Packing Option in the plugin settings.

With Box Packing & Pack Items individually options dimensions & weight will be considered to calculate the shipping cost. Refer the details below:

Parcel Packing: ELEX plugin provides you three options to pack a parcel(s) as given below:
Pack Items Individually:  In this option, each item in the cart is packed separately. Total Shipping cost calculated by adding shipping cost of each item.
For example, The shipping cost of Item X is $10. If the customer adds two quantities of Item X to the cart,  then total shipping cost is  $10 x 2, which is $20.
Note: This is the default option.

Pack into boxes with weight and dimensions: If packing items individually do not suit to your business, then you can define required box sizes under Box Dimensions section. All the cart items are packed into custom boxes defined in Box Dimensions settings. The best fit box is auto chosen from the defined boxes. This is the recommended option.You can read through setting up box dimensions to understand more in detail.

Weight based: In this option, the weight of all the cart item is summed up and passed to UPS API to get rates.
