Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureCutting sale prices usually means editing products by hand, forgetting to put them back, and hoping nothing else is discounted. PromoOS puts strikethrough pricing on a calendar: pick products, set the sale price and the dates, and it goes live and comes back on schedule, restoring the exact price and compare-at it saved, sale after sale. Conflict detection flags products already discounted.
DiscountOS lets you run different discounts for different markets from one place. Set up product, order, bundle, BOGO, tiered, volume, and shipping discounts that change based on Shopify Markets regions. Build precise targeting with AND/OR logic using customer tags, B2B status, login state, or purchase history. Create both automatic discount and discount codes that stack at checkout.
