Key elements include a detailed cart view with product images, names, quantities, and prices; order summaries displaying subtotals, taxes, discounts, and final totals; quantity adjusters for each item; delivery information input; payment method selection with support for various options like credit cards, digital wallets, and bank transfers; and a streamlined checkout process with clear calls-to-action. The screens also incorporate features like discount code application, tip options, and the ability to add new payment methods or select from saved ones.
