Now you can use multiple origin Zip Codes / Post Codes ( drop shipping )
There are two options to choose from:
*Set up a global origin zip code / post code ( standard method now available in most shipping plugins )
*Or add a origin Zip Code / Post Code at a product level.
You can use this shipping plugin for multi vendor functionality. You have vendors selling their products on your website, you can set up their products with there own origin Zip Code / Post Code.
This plugin will allow you to offer different services, for instance, Ground, Express, International.
Shipping rates will be provided for all the shipping services enabled, you could have five different origin Zip Codes / Post Code set up, rates will be combined together at the cart / checkout to offer the correct drop shipping rate.
As an example for a Ground shipping service:
Product A is shipped from 90213 shipping to 19026 the cost is $12.00
Product B is shipped from 08360 shipping to 19026 the cost is $9.00
Product C is shipped from 90210 shipping to 19026 the cost is $12.40
Product D is shipped from 63005 shipping to 19026 the cost is $12.00
Total Ground shipping cost is $45.40
What this plugin will allow you to set up:
Let’s just say you have four different Warehouses, each warehouse has it’s own origin. You can set up in the product area where the product will start the shipment from.
This will save your customers money as it is going to provide a true shipping rate.
This plugin can also be used with other multiple origin Zip Code / Post Codes ( drop shipping ) plugins at the same time, for instance you can use USPS and UPS at the same time with your products set up to ship from the warehouses they are located at.
*Origin Zip Codes/ Post Codes must be in the same country. You cannot set up multiple origin Zip Codes / Post Codes in different countries.

The box packer is volume based. This will in most cases provide good results, but will never be as accurate as a real person packing a box (see BIN Packing Problem) therefore it is important you understand that packing results are as accurate as they can be and any anomalies should be accepted.)
