SaleSync — Sale Scheduler

SaleSync changes your product prices when a sale starts and restores the original prices when it ends. Apply a percentage or fixed discount to your entire store, a collection, or a single product, and set the start and end times. Original prices are backed up before any change and customers see the markdown through compare-at prices, with no discount codes needed. You can end a sale early at any time, and the app makes no changes to your theme.
