Omnibus Price & EU GARAN, explained

Add the Omnibus lowest price block to your product template in the theme editor (and the collection embed if you want the line on product cards too). The overview tells you when the line is live, flags promotions to check, and explains what happens for products with less than 30 days of history — the line shows the lowest price since recording began, with its date, and becomes a full 30-day value automatically. One exception, on purpose: if a sale was already running when you installed the app, no price from before it is known, so the line stays hidden for that product instead of showing a made-up reference; it appears on the next sale.

When a product goes on sale (compare-at price above the selling price), the block shows the reference under the price: the lowest price of the 30 days before the sale started, with its date. It only appears during promotions, follows the selected variant, and is rendered by your theme with zero network calls — it doesn't slow your pages down. Font, size and wording are adjustable in the theme editor.

The Prices page lists what is on sale: price, compare-at, since when, the computed Omnibus reference and the window it comes from. A red badge warns when the sale price is above the reference — information only, nothing is changed in your store; review the sale price or the compare-at and decide.

One line per promotion and per variant: dates, compare-at, sale price, the reference price in force and what changed. Pick a period, download it as an Excel file (prices as real numbers, dates as real dates, opens correctly in any language) or as a CSV, and file it with your records — if an authority asks, this is what you show.

A typo fixed within 24 hours, a test price, an unpublished product — you can exclude such a price point from the reference, with a reason, dated and logged; the exclusion shows in the compliance report and is reversible. What you can never do is type in a higher reference: the reference is always a price that was actually charged. Declaring a lower price charged elsewhere is always allowed.

A single reference computed from your main prices is wrong as soon as a country pays different prices: another currency, a price adjustment, fixed prices or a sale that only runs there. The Omnibus rule is about the lowest price charged in that country. This app builds each country's reference from the prices actually observed there:

Good to know. For EU markets, Shopify can hide compare-at prices (Markets › your market › Compare-at price › Hide compare-at price for EEA customers). While they are hidden there is no crossed-out price, so no Omnibus line is needed or shown. Untick it when you want to show your sales with a crossed-out price in the EU: the app then shows the reference under it. The app needs permission to read your Markets settings (Shopify asks you once).

Since 27 September 2026, EU consumer law (Directive 2024/825, Regulation 2025/1960) asks every online store to remind shoppers of their legal guarantee of conformity, and to show the EU GARAN label when the producer gives a free durability guarantee on the whole product that lasts more than 2 years. The app covers both with the official EU artwork:

• Legal guarantee notice — every store. Turn on the EU legal guarantee notice app embed in the theme editor: one short sentence at the bottom of every page, and the full official notice (24 EU languages, with the link to europa.eu) opens on the first click. The EU guarantee label block does the same next to the price on product pages.
• GARAN label — only when it applies. Enter the producer guarantee in months (and, if you want, the brand and model) on the product, or in bulk from the Warranties page (by filter or by importing a spreadsheet, on every plan). From 30 months up, the product page shows the official nested label; the full label opens on click with only the three fields the regulation allows: years, brand, model. The app never invents a value — no guarantee entered, no label.
• Import from a spreadsheet — hundreds of products at once. Already have the guarantee durations in a supplier list or an ERP export? On the Warranties page, download the template, fill one line per product — its handle, or the SKU of one of its variants, then warranty_months, and if you want warranty_brand and warranty_model — and drop the file. Comma or semicolon, saved from Excel in any language, up to 5,000 lines. The app first shows a preview (products found, lines in error with their line number, products not found) and writes nothing until you confirm. An empty cell leaves the current value untouched: the import never clears a value.
• Checklist and switches. The Settings page shows what is in place (notice on, block added to your theme, products declared) and lets you switch the notice and the label on or off independently.

Zero JavaScript, zero cookie, zero network call: the notice and the label are rendered by your theme.

The EU guidelines also expect the legal guarantee notice in the order confirmation e-mail, with a reminder of the GARAN label. Shopify does not let apps edit notifications, so it is a one-time copy and paste from the app's Settings page. Follow the step-by-step guide with screenshots.

Since 13 December 2024, the EU General Product Safety Regulation (Regulation (EU) 2023/988, art. 19) asks every online offer to show clearly who made the product and how to use it safely. The app adds this to your product pages, on every plan:

• Once for the whole shop. On the Product safety page, enter the manufacturer — name or registered trademark, postal address and e-mail address — and, if you like, warnings that apply to all your products. A website is not accepted as the contact: the regulation asks for an electronic address, so the app requires an e-mail.
• Manufacturer outside the EU. Tick the box and enter the responsible person in the EU (importer, authorised representative or fulfilment service provider): the app does not save a non-EU manufacturer without it.
• Per product, when it differs. Pick a product to give it its own manufacturer, an identifier (type, batch or serial number) or its own warnings. The same fields are on every product page in Shopify (Metafields, “GPSR — …”), so Shopify's bulk editor and product CSV import fill them too. A product without its own manufacturer shows your shop default.
• On the storefront. Add the Product safety (GPSR) block to your product page from the theme editor (the page has a direct button). The information is always visible — no hidden tab — with headings in the 24 EU languages. Nothing incomplete is shown: a manufacturer without its address or e-mail stays hidden, and the page tells you what is missing.

Your text is never shortened: a value longer than the limit is refused with a message, and nothing is written. Zero JavaScript, zero cookie, zero network call on the storefront.

No plan limits the number of variants: every plan tracks your whole catalog. Free: 90 days of price history, the legal line, the guarantee notice and the GARAN label with bulk guarantee entry (GARAN is complete on every plan), product safety information (GPSR), one reference per EU country. Standard ($5/month): 1-year history, compliance report and full price history export (Excel or CSV). Plus ($12/month): 2-year history, everything in Standard. Change plan at any time from the app. Questions: support@merchanttools.eu.
