Excellent answer from Support (and fast, too!). My problem with setting a flat rate for shipping was not realizing it was an option under the Calculation Method on the Shipping page.
Here are the instructions for setting flat rate shipping to different countries from Support:
These flat rates can be created with Shipping Rules, and any other settings can be left alone. Here's a set of instructions based on our new interface that will create these rates:
First, mark the necessary products as shippable. Go to Seller Admin > View/Edit/Delete Products:
Select an existing shippable product of yours and click Edit;
If Shipping & Buyer's Address is not checked there, tick that box;
This will reveal several shipping options, which you can safely ignore. They aren't necessary for flat rate shipping:
- Weight:
- Package type:
- Capacity:
Click Submit to save settings;
Repeat this for all your tangible goods;
When adding new shippable products, remember to enable Shipping & Buyer's Address.
Next, go to Seller Admin > Shipping Calculations and set up the following:
Shipping Origin: select your country (and enter your ZIP code if you're in the US);
Limit Shipping Destinations: if you will only ship to certain countries, tick this box and select them in the list that will appear. This determines which countries can be selected in the cart;
Leave all other settings blank or 0.00;
Scroll down to the Your Shipping Rules menu, select and Delete any Rules you may have saved there.
Set up your first Shipping Rule for the US in the New Shipping Rules section below, using only these settings. You can ignore any not mentioned:
Calculation Method: Flat Rate per Order
Shipping Amount: 6.50
Destination Country: Select United States
Click Add Rule.
A second rule will set up shipping to Canada at a different rate:
Calculation Method: Flat Rate per Order
Shipping Amount: 9.50
Destination Country: Canada;
Click Add Rule.
A third rule will cover all other countries:
Calculation Method: Flat Rate per Order
Shipping Amount: 15.10
Destination Country: Select "All Countries" which will work as "all other countries" that aren't covered by the two previous rules;
Click Add Rule;
Click Back to Admin, and you're done!
