I am designing an iPad app. What is the best approach to present summary section in a shopping cart? For now, a have 2 versions:
- Ver 1. I grouped together Grand Total (in some cases it will be subtotal), Checkout button, PayPal and savings and have a separate section for all the summary including shipping, taxes, Gift Certificates, coupons, etc.
- Ver 2. I grouped all the details and checkout button in one group.
Which one is a better approach? and why?
