The delivery estimate card shows Prime eligibility and delivery info throughout the shopping journey, helping customers make confident purchase decisions. The card displays an estimated delivery date on product and checkout pages, updating to a more accurate estimate once the shopper signs in. MCF Fast Badges provide an option to show delivery estimates for items fulfilled by MCF but not eligible for Prime.

The delivery estimate card prompts users to sign in and appears in two states:

• Authenticated: Shown to shoppers who are signed in, offering personalized greetings, quick account access, and tailored recommendations.

• Unauthenticated: Shown to shoppers who are not signed in, using familiar language and trust-building elements to encourage sign-in.

Dos and don'ts

Design guidelines

Design options are available to customize the card’s appearance, ensuring it aligns seamlessly with your site’s style and enhances user engagement with tailored messaging.

Font and background color

You have flexibility to customize the font and card background color to align with your brand’s visual style. However, the Prime Check logo must remain unchanged, and any background color modifications must meet accessibility standards for readability and contrast.

Corner radius

Adjust the corner radius to align with aesthetic on your site.

	Square: Sharp, right-angled corners with no rounding. Use for a more professional, formal, or crisp look.
	Rounded (10 pixels): Partially rounded, strikes a balance between square and fully rounded. Common for modern sites.
	Pill (25 pixels): Fully rounded, radius container. Use for key actions, floating buttons, or an approachable, modern aesthetic.
	Custom (26-50 pixels): Choose your corners to match other containers and buttons on your site. Corner radius ranges are from 26-50px. Note that the estimate card is intended to be a card and not a button. Too large a radius can incorrectly give the impression of a button and confuse interaction patterns for your shoppers.

Message options

Delivery estimate card message options are personalized prompts designed to encourage Prime members to sign in. Messages feature the shopper’s name, dynamic delivery estimates, and eligibility for fast, free delivery and easy returns on eligible items in their order.
