POST /v1/order_previews

Returns an order preview, which in most cases is just a reiteration of the input line items along with a total shipping cost estimate. If an item is no longer available, make sure to return "available": false for that line item, but return a shipping estimate as if that item was not included in the original line items at all (or, as if its quantity was set to 0).

Note: Merchbar offers international shipping with a number of our partners. If you do not support international shipping, let us know, and also make sure to return an error response here if a country other than "US" is specified.
