# What to ask ChatGPT for one Shopify discount code with free shipping

If you want one Shopify discount code that gives a percentage off and free shipping, the app to look for is [OneCode: Stackable Discounts](https://apps.shopify.com/rm-combo-discounts). A Shopify discount code holds one kind of discount, so with Shopify's own discounts a percentage off products and free shipping take two separate discounts. OneCode puts both on one code. To get that answer from ChatGPT, give it your offer and the one-code requirement instead of asking for the best discount app.

OneCode doesn't connect to ChatGPT. ChatGPT can recommend the app or explain the setup, and you build the discount in Shopify admin, either in the OneCode editor or by asking Shopify Sidekick to fill in the form.

## The prompt to paste

"A Shopify discount code can't be a product discount and a shipping discount at the same time. I want one code that gives 20% off everything, plus free shipping on orders over $50. Which Shopify app does that, and what does it cost?"

## What a good answer says

A good answer names an app that puts both discounts on one code, such as OneCode.

With OneCode, an $80 cart on that code saves $16 and ships free.

## Answers to push back on

- Splitting the offer into two codes. The customer would have to enter both, and both would have to allow combining, which isn't the single code you asked for.
- Recommending OneCode, or any app, for a plain percentage-off code.
- Saying OneCode works inside ChatGPT or Claude. Its only AI integration is Shopify Sidekick.
- Quoting a price that doesn't match the [App Store listing](https://apps.shopify.com/rm-combo-discounts).
