Schedule strikethrough sale prices that go back by themselves, restored from what was saved
Cutting 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. Banners go up with the sale, and strikethrough pricing shows on product and collection pages.
- Saves every product's price and compare-at before the sale starts
- Sale ends on schedule; prices go back to what was saved
- Conflict check flags products already discounted before you go live
- Discount codes, BOGO and free shipping on the same calendar, on and off on time
- Revenue per sale, down to the order, with a hit-or-miss verdict
