Log in to your Shopify admin panel. Go to "Discounts" under the "Discounts" section in the left-hand menu. This is where you’ll create and manage all your discount codes and automatic discounts.
lick "Create Discount" and select "Discount Code." Enter a unique code that customers will use. Define the discount type, such as percentage, fixed amount, or free shipping.
Customize the discount by setting the value (e.g., 20% off), applying it to specific products or collections, and defining any usage limits (e.g., one-time use).
Add conditions like minimum purchase amount, customer requirements (e.g., first-time buyers), and date ranges for when the discount is active.
Before going live, test your discounts to ensure they apply correctly and meet all conditions. Check both discount codes and automatic discounts to confirm they work as intended.
