FlashPrice: Sale Scheduler

Run sales without editing prices by hand. Pick a collection, tag, vendor, product type, or a CSV of SKUs and prices. Set a percentage, amount, or fixed price, preview every variant, and adjust any price before scheduling. At the start time FlashPrice records each variant's exact price and compare-at price, applies the sale, and restores everything when it ends. A price you edit during a sale is left alone and flagged. Edit, extend, or duplicate sales, with an email when they start or end.
