Sam's Club implements a checkout marred by forced registration and a 5-page layout.
Individual forms are clean and usable - error notification is clear - but there are too many added steps that increase friction. In addition to forced registration, many fields, such as credit card numbers, are hidden behind links and dropdowns (example: "Add Credit Card" instead of simply showing the card field with a "save card" option).
The Sams Club Desktop Checkout complies with 46% of our recommended best practices.
