Shopping Cart screens in React Native ( web supported )

We are developing a delivery app and we still need the development of some screens, one of which, is the cart of the app. The app deliveries Milk and skimmed milk. Therefore, on the cart, the user should be able to set how many of each he/she whats for each day of the current week. So there should be a table with 3 columns (Day of week, Number of Milks, number of skimmed Milks). Below the table, there should be the summary of the order: How many mils in total, how many skimmed milks in total, total of the order. There should be a place to select the payment method. (credit card, money) And the finish order button will be at the bottom of the page. The json sent to the back end should be on this format: { deliveries: { { count: number countSkimmed: number dateToDelivery: timestamp } } } The screen should be design friendly, and the user should be able to set the number of milks no the rows of the column.
