# One code for the whole campaign.

Black Friday, influencer codes, and a welcome flow, each built on one OneCode discount.

- [Black Friday on one Shopify code](/campaigns/black-friday.md): Plan Black Friday around one code with 20% off and free shipping over $50 that ends by itself, plus creator codes that still work during the sale.
- [Influencer codes on Shopify, with one setup for every creator](/campaigns/influencers.md): Give every creator their own code for 10% off the order and free shipping, all from one discount that still works during a sitewide sale.
- [A welcome flow with one code for 10% off and free shipping](/campaigns/welcome.md): Put one code in your welcome popup and email that gives 10% off and free shipping, limited to one use per customer or to first-time customers.
