# For Scripts migrations, Plus stores, and agencies.

Rebuild a discount Script as one OneCode discount, stack product discounts on Shopify Plus, and set up offers for client stores.

- [Replace a Shopify Script that combined discounts](/for/shopify-scripts.md): Rebuild a Script that gave a product discount and free shipping together as one OneCode discount, which runs as a Shopify Discount Function.
- [Stack two product discounts on the same item on Shopify Plus](/for/shopify-plus.md): On Shopify Plus, OneCode can let two tagged product discounts apply to the same item. On other plans, each item gets only the better product discount.
- [OneCode for agencies running Shopify discounts](/for/agencies.md): Build each client's offer as one Shopify code that holds product, order and shipping discounts, using the same setup on every store.
