Magento 1.9 – Shipping Methods Not Showing Up in Multiple Websites

With regards to Ground if you have the Set Residential to Yes then FedEx will not return Ground, it will only ever return Home Delivery.

If International Economy is not showing then for the goods you have in the cart and the destination you are specifying its not an available option. I suggest go enter direct into FedEx exactly the same weight and destination then see what it says there.

By default that isn't possible, you must, at least implement:

• A custom Shipping Method
• A custom Shipping Form for your method, to allow customer select different shipping method for each item.
• Create sales_quote_item and sales_order_item attributes to save customer method selection

Your custom shipping method must handle all that logic, you need to split all items/weights and calculate the individual/total shipping cost/price and eventually some combination too ie:

- item 1 by usps = $10.
- item 2 by usps = $10.
- item 1 and 2 by usps = $15

Your shipping method must be able to:

• Obtain the shipping cost/price from the others shipping methods (for each single or combination possible item selection)
• Save customer shipping selection to sales_quote_item
• Recalculate all that data in all further steps in checkout
• Save quote_item data to order_item
• Re-implement any other -parent- shipping method feature, like Api calls for pickup, packages generation or tracking number getters

Finally if you want to give your customers a good communication feedback, you should modify all "post place order" email and templates in order to display all that information.

IMO is a lot of work to do, and I can't figure out a real-life case in which such effort would by justified.

EDIT

I'm not totally sure, but a partial use of some dropship extension may help... I guess
