Get real time shipping rates (domestic & international) from the USPS website for your PrestaShop 1.7.x store.

Shipping rates are calculated by weight and dimensions or one of the USPS boxes.

Single Box - Assign one box size which will be used for all products:

Multiple Boxes (Fixed Size) - Define how many products can fit in a box (number), or calculate only by weight.
Multiple Boxes (Product Dimensions) - Define all the box sizes you use for shipping, assign dimensions to your products, and the module will automatically calculate (using an algorithm we developed) how many boxes are needed to fit all the products (always trying to use the smallest / lowest number of packages).

Ability to have free shipping by Product, Category, Manufacturer or Supplier.

You can select which shipping options should be available.

Each shipping method can have its own Free Shipping Limit, Additional Fee, and Insurance (international only).

Q) What is the difference between this module, and the USPS module that comes with Prestashop?


A) The USPS module that comes with Prestashop (and many other USPS modules for other carts) are very limited when it comes to calculating the boxes that are used for shipping.

They generally offer 2 options:

1) Place all the products in 1 box with a fixed size - This can cause high estimates, as a small product and a large product will share the same box size (which would have to be big)

2) Place each product in its own box - This causes even higher estimates, since using 2 boxes instead of 1 larger box is more expensive.


Our module uses an advanced algorithm (developed by our team) to calculate products / boxes.

It lets you specify multiple box sizes that you typically use for shipping, when products are added to the cart, the module automatically calculates how many boxes / which sizes are needed to fit all the products. It will always try to use the fewest boxes and the smallest sizes.

This provides the most accurate rates for your customers.


Our module lets the customer see a preview of the shipping rate for each product (no login required), as well as the ability to set a free shipping limit per shipping method and zone.
