Delta lets you change prices for many products and variants at once instead of editing them individually. Apply a percentage increase or decrease as a general update, or as a campaign that sets the compare-at price to show a discount in your store. Filter your selection by collection, product name, tags, or price range. Every action is saved, so you can undo it to restore previous prices or reapply it later. You can also schedule changes and automate pricing with rounding and inventory rules.
