OmniPrice Guard support
Help with installing, setting up and using OmniPrice Guard.
What the app does
OmniPrice Guard records every price change in your Shopify store, works out the prior price the way the EU price reduction rule describes (the lowest price of the 30 days before a reduction started), keeps it fixed for the whole promotion and shows it on your product pages. It also flags strikethrough prices that do not match and gives you a timestamped price history export. It supports your compliance work and is not legal advice.

Frequently asked questions
Does OmniPrice Guard make my store comply with the rule?
It supports your compliance work by recording prices and showing the prior price. Whether your store complies depends on how you set prices and which countries you sell to. It is not legal advice, so check your obligations with your own adviser.
Why is the prior price not showing on my storefront?
Check that the app embed and the Prior price block are enabled in your theme, that your plan is active, that the variant has a live promotion with a verified prior price, and that the visitor is in one of the countries you chose in Settings (or that you chose none, which shows it to everyone).
What happens if I choose no countries?
The prior price is shown to all visitors. Once you choose one or more countries, only visitors from those countries see it. The dashboard reminds you until you choose.
How long until I have a full 30 days of history?
The app starts recording when you install it. Until it has 30 days of prices, prior prices are marked "history incomplete". Prices recorded before you installed are not available.
Why does a warning say the strikethrough does not match the prior price?
The compare-at price shoppers see is different from the prior price. Use the fix button to set it to the prior price, or remove the compare-at price. You can also turn on automatic fixing in Settings.
Do discount codes and automatic discounts count?
Not in this version. They do not change the displayed product price, so they are not tracked. Product prices, compare-at prices and Shopify Markets prices are.
What happens if I cancel?
Price recording, detection and warnings keep working, but the prior price stops showing on your storefront. The dashboard lists products that still have a compare-at price so you can remove it. Uninstalling the app removes its theme block and its stored data, which we delete after Shopify sends the shop/redact request.
How do I get my data out?
Use Price history export in the app to download a timestamped CSV for any date range or product.
