Prioritize for purchase using the Shopping Cart. Cartblanche contains a shopping cart feature that allows molecules found in a search to be retained for further processing (Figure ). The cart supports reviewing molecules and their purchasing information, links to identify additional analogs, and removing individual molecules. An approximate price estimate is calculated in the hope that it will provide some useful guidance, but only the vendor can provide the true price. For users that register and sign in, multiple carts allow multiple projects to be pursued in parallel. The cart can be formatted into google sheets, as an Excel spreadsheet, as a PDF, or as plain text, to assist with routing this information to the vendor for a price quote.
