Every Advanced Proposal can generate and print a comprehensive Shopping List of your Components across the entire Proposal. So this will include each Flower or Supply component you've added to an Item, and it's Cost, Markup, and Quantity.

Think of it is as a printable version of the Estimate feature, but one you could take to your wholesaler, local market or distributor. 

You can access it by locating and clicking the Print button at the top of the Proposal you are working on and selecting Shopping List.
