Checkout Flow

The Rule: Fewer Steps = Higher Conversion

• Guest checkout option (always)
• Single-page checkout when possible
• If multi-step: show progress, allow editing previous steps without losing data

Cart Design

• Show item image, name, quantity, price
• Easy quantity adjustment (+ / - or input)
• Remove item with confirmation
• Show subtotal, taxes, shipping, and total clearly
• Promo code field (collapsed by default, not prominent)
