I want to run a 'Buy one foundation, get one 50% off' promotion. How do I set that up?

I'm looking to create a strategic 'Buy one foundation, get one 50% off' promotion for my cosmetics store. I want to increase sales of my foundation line, encourage customers to purchase multiple items, and create an attractive offer that feels like a genuine value. However, I'm unsure about the technical implementation, potential pitfalls, and how to structure this promotion to maximize its effectiveness without hurting my profit margins. What are the best practices for setting up a successful BOGO-style discount campaign?

TL;DR - Quick Answer

Use Shopify's Buy X Get Y discount type. Set 'Customer buys' to 1 item from your foundation collection, and 'Customer gets' to 1 item from your foundation collection at 50% off. This is a native Shopify feature requiring no apps.

Setting Up a Buy One Get One 50% Off Promotion

BOGO at 50% off is more margin-friendly than a fully free item and often converts at similar rates because the framing "get one at half price" feels like a deal without the full cost of a free product. Here's the exact Shopify setup.

BOGO Timing with Growth Suite

Growth Suite's Post-Purchase Upsell Funnels are a strong complement to BOGO deals - after a customer buys one foundation at full price, a post-purchase page can offer the second at 50% off. This captures the BOGO benefit without requiring the customer to know about the deal upfront, which preserves full-price intent while still driving incremental sales.
