I plan on selling products from multiple suppliers. How will the shipping calculations work?
There is provision for only one shipping origin in the Packaging Options of your store admin and there is no way to specify different ship rates on a per supplier basis. We are looking at that possibility but it requires extensive & complex changes to the store codebase. What most people do is setup a basic shipping scheme using a table rate that charges based on % of order total or based on the total weight of the order. If your profit margins are correctly set, even though you will not match all suppliers shipping rates exactly, you will be pretty close. USPS and UPS can also be used to provide real time quotes – if your suppliers are in vastly different locations, use a ship origin zip code which is somewhere in the mid-us region – that way your shipping rates will balance out over many orders. You can also use the ship rate override field in the product editor to set a specific shipping value for products which will override the normal rates.
