Ecommerce Product Sale Instagram Post Prompt

Create a square 1:1 Instagram promotional post for an ecommerce store, DTC brand, or online retail business. Feature a clean product hero image, bold sale headline, discount badge, benefit-driven supporting copy, and a clear shop-now call-to-action. Use a modern retail layout with premium lighting, crisp product shadows, balanced whitespace, and mobile-readable typography. Include placeholders for {brand_name}, {product_name}, {sale_headline}, {discount}, {benefit_line}, and {cta}. Make the design suitable for Instagram feed ads, carousel covers, and ecommerce remarketing campaigns. Avoid visual clutter, unreadable text, fake platform UI, watermarks, and copyrighted brand marks. Layout safety requirement: reserve separate safe zones for headline text, supporting copy, CTA buttons, discount badges, and the main product or illustration. Do not let text, badges, buttons, icons, or product artwork overlap. Keep all copy readable on mobile with generous padding and balanced negative space.
