Run your sale. Get every price back.

SaleGuard is a Shopify app for store-wide and scheduled sales that records every original price before it changes, checks every update actually landed, and restores prices exactly — with one click or automatically when the sale ends.

Why merchants use it

Prices never get stuckEvery original price is written to a price history before the sale touches it. Undo puts back exactly what was there, even if something changed mid-sale.

No silent failuresEvery price is read back after it is changed. Anything that didn't take is reported as failed, never counted as done.

Preview before anything changesSee exactly which prices would move, and to what, before you press Apply.

Your prices are never hostageDownload the full price history as a spreadsheet at any time, including after you uninstall.
