Screen-free virtual assistants, e.g., provided via smart speakers or appliances, are often used for online shopping by issuing voice commands. Prior to checkout, a user often finds a need to remove some items, e.g., due to cost or other considerations. When the device lacks a screen that allows viewing the shopping cart, it is difficult for the user to determine an optimal combination of items to remove such that high-priority items remain in the shopping cart and the shopping cart remains within budget.
This disclosure describes techniques that enable a user to command a virtual assistant to automatically prune a shopping list to stay within budget. The virtual assistant determines the items that stay in the shopping cart by removing the least important items from the cart, by reducing the quantity of items that cannot be dropped from the cart, or both.
