The Overview/Summary screen is the first page you will be brought to after selecting to go to your cart. This screen can be used to get a full look at your order, make changes to quantities, and get detailed information about your order. By default you will start at the Overview screen, to switch to the summary screen select the 'Summary' button in the top right.
The 'Overview' screen is a detailed look at each of your shipments which are organized by column and style in your order displaying in rows. At the end of your shipments there is a total that shows the total amount of each item combined from your shipments. The very last row will display the overall total of each delivery and order total. At the very bottom of the page you will see the order total with any discounts you qualify added in. This is the last screen to double check your orders items and quantities before being submitted.
In the top left you can change the order that your shipments display.
Catalog Order - Sorts the products by the order they show in the catalog
Manual Sort - Sorts the products by how they are ordered in your 'Build Order' screen.
Name Order - Sorts the products alphabetically by name
Price Order - Sorts the products by price low to high
Next to each shipment you will see a edit button you can select, by selecting this button it will bring you back to the 'Enter Quantity' screen to make changes to your shipment. The same edit button next to each unit can be selected to add/change quantities of each product from the overview screen.
Quantity can also be dragged and dropped between shipments if you want to move quantities from one delivery to another.
Switching to the 'Summary' screen gives you a breakdown of your order. This screen can be customized by selecting different 'facets' from the drop down (circled in red), adding a row of that facet. The facets (circled in blue) can be dragged and put in your preferred order. Using the top tabs the shipments can be analyzed as a whole or separately.
