Repeat customers add products to their cart but are not checking out

Creating registration for customer accounts can streamline the checkout process for repeat customers by pre-filling their shipping and billing information. This reduces friction and the likelihood of cart abandonment. While customer reviews (A) can build trust and encourage purchases, they don't directly address checkout friction for repeat customers. Introducing responsive design (C) ensures a good user experience across devices, but it doesn't specifically solve the problem of repeat customers abandoning carts at the checkout stage due to cumbersome data entry.
