SaleGuard: Bulk Sale Scheduler

Schedule a Black Friday, holiday or flash sale once. At the start time SaleGuard changes prices in bulk and shows the original as a strikethrough compare-at price. At the end time it reverts every variant to the exact price it had before.Originals are saved before anything is written, so a second run cannot stack discounts. If a variant fails, you retry only that one.Also included: volume, cart, buy X get Y and free shipping discounts.
