From the Shopify dashboard, click on Products.

Find the product you're looking for.

Click the name of the product to bring up the Product Page.

From the Product Page, scroll to the middle of the screen to find the Pricing section.

In the Price field, highlight the price of the product and enter a new value.

Once you're done, a save bar will appear at the top of the screen.

Click the Save button to push your changes to the front end of Shopify.

Navigate back to the Products page.

Locate a variable product.

Scroll down to the center of the screen and you'll find that a variants section has replaced the Pricing section.

Drag the scroll bar to the right until you see the Price field for each product variant.

Enter new price values for your product variants.

Click the Save button to push your changes to the front end of Shopify.

Navigate back to the Products page.

Select any number of checkboxes next to your list of products.

With multiple products selected, click the edit products button at the top of the screen to bring up a new page. Right away you'll see that each of your products are listed in a series of rows, each with a Price field readily available. Additionally, you'll notice that for variable products, each variant is displayed individually on this page, making it much faster for you to edit product prices from this screen than from the individual product pages.

Enter new prices for any number of products.

Click the Save button and you're all set.
