B&H Photo Video implements a multi-page checkout. Although B&H only uses one column to keep form fields relatively short, each form could still be made to feel faster and simpler. Short fields (First/Last Name, and City/State/ZIP) can be placed on the same line, saving space and making it easier to convert to a true single-page checkout.
Making guest checkout the default would also help, currently there is a pop-up when entering the checkout asking for logins or account creation, with the guest checkout option being the third and least visible one listed.
The B&H Photo Video Desktop Checkout complies with 87% of our recommended best practices.
