# Black Friday Claim Check: Make your Black Friday 'was' prices the 30-day low, and watch rivals' cuts as they land.

> In the EU, the 'was' price on a Black Friday banner must be the lowest price you charged in at least the 30 days before the reduction, and the '% off' must be computed from it. RivalSweeper records prices daily from the day a store is added and checks your reductions against that record.

- For a reduction starting 27 November, the look-back runs from 28 October; earlier deals start it earlier
- Planned reference prices and '% off' checked against the lowest recorded price
- Rivals' price and promotion changes surfaced within 48 hours, with per-SKU discount depth

## The price you set in October becomes the reference price in November

Black Friday 2026 falls on Friday 27 November. An announced reduction in the EU must show the lowest price applied in at least the 30 days before it, so a deal starting on 27 November looks back to 28 October. A Black Friday week that opens on the 20th looks back to 21 October.

That puts your October trading decisions on the line. A flash sale in early November or a Singles' Day cut on 11 November can become the 30-day low your banner has to quote, and since Aldi Süd the '-40%' must be calculated from that low. Checking it needs a daily record that started before the look-back did. RivalSweeper's record for a store starts the day it is added, so the time to start is now.

## From now to 27 November

1. **Start recording now.** Book the free call to get your store's product pages recorded; the record runs from the day they are added. Add rivals on a monitoring plan; first data within 24 hours.
2. **Check the plan before launch.** Planned reference prices and percentages for your hero SKUs are compared with the lowest price recorded in the look-back.
3. **Watch rivals through the event.** Rivals' price and promotion changes surface within 48 hours, with effective price after every discount.
4. **Check what went live.** Displayed claims are set against recorded prices, the discount recomputed, gaps listed. Keep it for later questions.

## Features

- **30-day low per product.** The lowest recorded price in the 30 days before each reduction, and the date it applied.
- **Banner percentage recomputed.** The '% off' recalculated from the 30-day low, so an overstated badge shows before the banner ships.
- **Look-back follows your start date.** Each reduction is measured back from its own start date, so early-access deals get their own window.
- **Rivals' Black Friday moves.** Effective price after discounts, plus every price and promotion change within 48 hours, on rivals' own storefronts.
- **Discount depth across your set.** Per-SKU discount depth ranked across rivals, with history. Only verified markdowns count, never a standing 'compare at' price.
- **Clearance signal.** A product marked down 40% or more and now sold out shows as cleared, so you can tell clearance from promotion after the event.

## Who it's for

- **Trading managers who own the promo calendar.** You set Black Friday depth and timing. You see which October and November prices will become your 30-day low.
- **Promotions managers writing banners.** You publish the '-30%'. You get the reference price and percentage the record supports, product by product.
- **Heads of ecommerce selling cross-border into the EU.** Each market is recorded in its own currency, and you watch rivals in those markets through the event.

## Compared with the alternatives

- **Screenshotting your own pages daily.** Possible for a few hero SKUs; not for a full Black Friday range across markets for 30 days.
- **Your back-end price export.** Shows the price set, not always the price displayed, and nothing about rivals.
- **Enterprise price-intelligence suites.** Built for large pricing teams and live competitor comparison, not for testing your own reductions against a 30-day low.

## FAQ

### When do we need to start recording?

At least 30 days before your reduction starts: by 28 October for a deal starting on 27 November, earlier for earlier deals. The record starts the day a store is added and is never filled in backwards.

### Is the reference price the price before the sale?

Not necessarily. It is the lowest price applied in at least the 30 days before the reduction, which may be an earlier sale price.

### We run deeper cuts through Black Friday week. Does each step reset?

The directive lets member states allow, for progressively increased reductions, the price before the first reduction as the prior price. Whether your markets use that option is for your counsel to confirm.

### Will we see the moment rivals launch?

Price and promotion changes on supported websites surface within 48 hours, not in real time.

### Can the free trial cover this?

The trial runs 14 days, covers 1 rival and the last 30 days of history, and needs no card. When it ends access pauses and nothing is charged; a paid plan keeps tracking through the event.

### Is this legal advice?

No. This is not legal advice; RivalSweeper is not a law firm, and we do not promise admissibility in any court; that is for counsel to decide.
