SaleGuard: Bulk Sale Scheduler

Sales are easy to start. The expensive part is the morning after, when some prices are still discounted and you cannot tell which ones.SaleGuard records price and compare-at for every variant before it writes anything. When the sale ends it writes those values back and lists any it could not, so you retry only those. Restore does no arithmetic, so a second run cannot compound.Runs to the minute in your timezone. Never touches your theme. Volume, cart, buy X get Y and free shipping included.
