Ecommerce brands are getting sued over fake-discount ads. Is your Shopify catalog exposed?

What counts as a “fake discount” under U.S. law

A strikethrough or “was/now” price on a Shopify product page is a factual claim: the seller is asserting the product previously sold at a specific higher amount, and the current amount is a real reduction from that reference. The Federal Trade Commission’s Guides Against Deceptive Pricing, codified at 16 CFR Part 233 (the FTC’s longest-standing consumer-protection guidance on this specific question), makes that a deceptive practice under Section 5 of the FTC Act when the reference price was not a bona fide, substantial-volume prevailing price the seller genuinely offered for a reasonable prior period.

Every state layers additional rules on top of the federal baseline. California Business & Professions Code §17501 is the strictest of the frequently-litigated statutes: it treats a “was” price as deceptive unless the higher amount was actually charged for a reasonable period of time in the three months immediately preceding the sale. New York General Business Law §349 sweeps in any deceptive act or practice in trade or commerce and has supported private class actions against ecommerce sellers for pattern-of-conduct fake-discount claims. For cross-border sellers into the European Union, the EU Omnibus Directive (Article 6a of the Consumer Rights Directive) requires that any announced price reduction show the lowest price the seller applied during the 30 days preceding the reduction, not the highest.

In plain terms, a Shopify store that ships a $79 shirt at “$79 (was $149)” is only in the clear if that store can show it actually offered the shirt at $149 for a defensible recent stretch, a stretch that, depending on where the buyer is, ranges from a “reasonable prior period” (FTC) to 30 days (EU Omnibus) to 90 days (California). A permanently-strikethrough “was” price the store never actually charged, or only charged for a token 24 hours to unlock the higher anchor, is the exact scenario the Guides Against Deceptive Pricing were written to address.

Why merchant risk is going up right now

Reference-pricing compliance is not a new area of law, the FTC guidance dates to 1964, but enforcement activity has visibly re-intensified over the last two years, with a mix of FTC advertising and marketing guidance refreshes, state attorney general actions, and a growing docket of private class actions filed under state consumer-protection statutes. Retailers of the scale of Wayfair, Best Buy, Nike, and Shein have each faced 2026 filings alleging permanent-strikethrough-price patterns. Those cases settle, or they don’t, but either way the discovery burden of proving a defensible reference-price history for every SKU on a catalog of tens of thousands is real and expensive.

Mid-market Shopify merchants are not being sued because they specifically decided to run fake discounts. In almost every operator conversation this pattern shows up because the “compare-at price” field on a Shopify product was set once by a copy-paste from a vendor sheet, or by a launch-day promotion that ended six months ago, or by a bulk import from an old catalog, and nobody has audited the field since. Shopify’s admin UI renders the strikethrough exactly the same way whether the reference is a bona fide prior price or a made-up anchor. There is no built-in Shopify feature that flags the “compare-at” against a compliant recent-price history, because Shopify itself does not claim to enforce state or federal reference-pricing law on merchants’ behalf.

That is the gap PriceProof monitors. Every SKU on your storefront gets a continuous price-history record. Every “compare-at” or displayed strikethrough gets evaluated against jurisdiction-appropriate windows (30 days for EU-shipping stores, 90 days for California-shipping stores, “reasonable prior period” for the federal baseline). Every flag comes with the specific statute or rule that triggered it, so your team, or the counsel you already work with, can decide whether to leave the reference alone, remove the strikethrough, or lower the “compare-at” to a defensible amount, before an enforcement letter or a class-action complaint forces the decision.

Why the price-history database is the whole point

A compliance tool that just reads your Shopify catalog once, right now, cannot tell you whether a “compare-at $149” is defensible. The defensibility test is historical: what did this SKU actually sell for during the 30, 60, or 90 days before the reduction was displayed? That evidence has to be captured continuously, timestamped, and stored, not reconstructed after the fact. Every week a merchant does not have a price-history capture running on their catalog is a week of forensic evidence they cannot go back and produce if a state AG or a class action asks for it.

PriceProof’s plan is to run scheduled catalog scans (planned: hourly for paid plans, daily for the starter tier) that record every price change on every SKU, and use that history as the ground truth against which every displayed strikethrough is evaluated. The longer the tool runs on your catalog, the stronger the “we can affirmatively prove this reference price was actually charged for X days” record becomes. That accumulating history is the point of the product, not the individual scan, not the individual flag.

Planned pricing at launch

Planned pricing at October 2026 launch is $79/mo for a single store and $149/mo for the agency plan with multi-store support, both with a 25% annual discount and monthly cancellation. No Stripe SKU exists today, and the numbers on this page are prose-only, they are not embedded in this page’s product schema so search engines will not index a Product/Offer that a real Stripe checkout cannot fulfill yet. Waitlist members get launch-week pricing locked when checkout opens.

PriceProof is a sibling product to PixelProof, which monitors Shopify Meta pixel, GA4, and GTM tracking against the platform-side changes that break attribution. Same build-and-ship team, same operator, same clear billing surface. The two products share underlying infrastructure (the price-history capture will run on the same scan infrastructure Piper, sorry, PixelProof, already uses for tracking-tag capture).

Why we’re building PriceProof

PriceProof is the second in a compliance-monitoring product line Digital Empire Holdings LLC is shipping in the second half of 2026. The first, PixelProof, monitors Shopify tracking-tag health against the platform-side changes that silently break attribution. PriceProof extends the same “continuous monitoring plus paste-ready fixes” pattern to the specific compliance surface, reference pricing, where merchant risk has visibly increased in 2026 and where zero direct incumbent exists at the price point mid-market Shopify sellers can actually adopt.

We are shipping this pre-launch page five weeks before the target launch date for exactly one reason: to prove there is measurable pre-launch demand for the product before the engineering work begins. If nobody joins this waitlist, that is a real signal the tool is not worth building, and we’ll say so publicly rather than shipping a solution nobody asked for.

Frequently asked

• Is PriceProof live today?

  No. PriceProof is targeting an October 2026 launch after PixelProof (its sibling product) clears its M2 revenue gate. This page is a pre-launch waitlist so you get first access, launch-week pricing, and a direct signup link the moment PriceProof opens.

• What is a "fake discount" under FTC law?

  The FTC Guides Against Deceptive Pricing (16 CFR Part 233) treat a strikethrough or "was/now" price as deceptive when the "was" reference price is not a bona fide, substantial-volume prevailing price the seller actually offered for a reasonable prior period. State laws (California Business & Professions Code §17501, New York General Business Law §349, and the EU Omnibus Directive for cross-border sellers) go further, California requires the higher price to have been actually charged in the 90 days immediately preceding the sale.

• What does PriceProof actually monitor?

  PriceProof scans your Shopify catalog on a schedule (planned: hourly for paid plans) and flags any strikethrough or "compare-at" price whose reference does not have a compliant recent-price history in our database, plus jurisdiction-specific rule violations (California 90-day, EU Omnibus 30-day, New York disclosure). Every flag comes with the FTC or state-law citation triggering it so your team or counsel can evaluate the risk.

• Why is a price-history database the moat?

  Compliant reference pricing is defined by what the seller ACTUALLY offered over a prior time window (30 to 90 days depending on jurisdiction). That evidence has to be captured continuously, a compliance tool that starts capturing today cannot retroactively prove what your prices were last month. Every week PriceProof is not yet running on your catalog is a week of forensic history you cannot get back.

• How is this different from Shopify's built-in "compare at price" field?

  Shopify's compare-at price is a UI feature, it renders the strikethrough visual but does no compliance validation. PriceProof reads the same field and checks whether the compare-at value has a defensible history under FTC and state law, plus applies jurisdiction rules that Shopify itself never claims to enforce.

• When will paid plans open?

  The Aug 2 2026 spec locks planned pricing at $79/mo starter (single store) and $149/mo agency (multi-store) with a 25% annual discount, targeting October 2026 launch after PixelProof M2 clears. These numbers are subject to change before launch, no Stripe SKU exists yet, so nobody can accidentally get charged from this page. Waitlist members get a locked launch-week price when checkout opens.
