Filter your shop products with a text search or a filter on the collection, then enter a percentage and click on the "apply discount" button. The app allows also to restore the original price because the price is moved to the "compare at price" field for every product in sale. Clicking on the "restore original prices" will move the content of this field into the discounted price, overwriting it. Please be careful using this app: with great power comes great responsibility!
