When using the multiple "ship from" feature, how do I associate a product with a ship from address. Many of my products are drop-shipped from different sources.
In order to set your shipping rates by product using the multiple ship from option, you may select your Shipping Calculator by "Unit" (Settings/Shipping). You will also need to identify how many ship from addresses you will be using, as well as select Independent Shipping (Settings/Site Options). Then, go to the next page to enter the multiple ship from addresses. Then, go to each of your products, select Ship From option near the top of the page, then set your Shipping Rates on the next page.
