Buy X Get Y promotions — buy two, get one free; buy one, get one half off — are some of the most effective ways to lift average order value. They nudge customers to add one more item, and they feel generous without giving away your whole margin. The catch is that store owners often think they need a paid bundling app to run one.
You don't need an app for this
Shopify actually supports Buy X Get Y discounts natively, but the setup is buried and easy to misconfigure: choosing the customer-buys quantity, the customer-gets quantity, which collections each side applies to, and whether the reward is free or discounted. One wrong field and the deal either doesn't trigger or applies far more broadly than you intended.
Describe the offer in plain English
With Claude MCP Connector, you state the deal and Claude configures the native discount correctly:
Claude sets it up to auto-apply at checkout — no code for the customer to remember — and makes the lowest-priced item the free one, so the math works in your favor.
Variations you can run the same way
Why it's worth doing often
Because there's no app subscription and no fiddly setup, BXGY stops being a once-a-year event. You can spin one up for a slow collection, a holiday weekend, or a product you're overstocked on — each one a single message, live in seconds, and gone again when you say so.
