WARNING: Promo prices set here will apply to ALL inventory items in the category. It might be better to assign promo prices to individual items or create additional categories.
Choose the Add or the Edit button to set dates, times, and discount percentages.
When assigning Promo Pricing for a category, the only logical option is to set discount percentages because each individual item will have varying costs and selling prices.
