Issue

Title and steps come from the upstream issue and pull request.

Description

The order is placed using the $6.00 In-Store Delivery shipment method, which is NOT the cheapest shipment method.

{quote}As seen in the screenshot, with my setup, the order placement does not finish successfully and ends with a "Quote does not have Pickup Location assigned" error. The cause of this error is irrelevant to the bug described in this issue. However, the fact that it gives *this* error in particular shows that the instant purchase flow attempts to place the order using the In-Store Delivery shipment method, which is sufficient to demonstrate the bug.

Steps to reproduce

* On the frontend page, make sure you are logged in with the previously created customer account.
* Click on the “Search entire store here…” textbook, type “Chaz Kangeroo Hoodie”, and press Enter.
* There should be only one result. Click on it to open the product details page for “Chaz Kangeroo Hoodie”.
* Click on the Instant Purchase button. You’ll see a confirmation popup with Shipping Method: Cheapest price.
* Click on OK to confirm the purchase.

Expected result

The order is placed using the cheapest shipment method, which, as we saw in step 6, is the $5.00 Flat Rate shipment method.
